Backwashing the Marlin Hydro Vortex™ Medium Waterfall Filter
Hydro Vortex™ waterfall filters combine high surface area media, a vortex solids separator, settling cone with a bottom drain for complete and efficient backwashing. Hydro Vortex™ waterfall filters do not require blowers or air pumps for backwashing.
The Marlin Hydro Vortex™ medium waterfall filter is the mid-size of the industry-leading Patented Hydro Vortex™ series of completely backwashable biological waterfall filters. Invented by John Russell, a Hydro Vortex™ medium waterfall filter is cleaned simply by opening its included drain valve and reversing water flow through the filter. This can be done either manually or mechanically with our exclusive HydroFlush™ Backwash System.
The HydroFlush™ option uses your existing pump and the included 3-way valve to reverse water flow through the filter. Cleaning a Marlin Hydro Vortex™ filter with the HydroFlush™ system is as easy as turning two valves!
The dirty water exiting the filter's drain pipe is loaded with nutrients! Use this backwash water to organically fertilize your landscape and gardens.
Hydro Vortex™ waterfall filters are designed for periodic gentle back-flushing of fish waste, mulm and detritus instead of the massive disruptive heavy annual pressure washer cleaning required for typical "Pad-&-Media-Bag" type waterfall filter boxes. Don’t be misled by the claims that say biological waterfall filters only need "annual cleaning" – the health of your fish may be at stake. All medium waterfall filters, no matter what type or brand, benefit from periodic rinsing of fish waste, mulm, and detritus.
Commonplace “Pad-&-Media-Bag” type waterfall filters are not designed with bottom clean out drains for ease of cleaning and routine gentle back-flushing. Soiled waterfall filters can cause poor water quality and can encourage algae growth and fish disease.
Biological waterfall filters – of any kind or brand – that are not periodically back-flushed will eventually plug with fish waste, mulm and detritus (the build-up of fish and bacterial waste that looks like brown goop).
If the fish waste, mulm and detritus isn’t periodically back-flushed it can clog the filter media – no matter what type. Clogged filter media can cause the water to start “channeling” around the filter media within the filter. This means that water is finding a path of least resistance around the clogged media.
Water that channels around the filter media isn't being filtered. Water passing around the media through channels causes other areas within the filter to have stagnant, non-moving, oxygen-deprived water.
Areas within the filter that don’t pass oxygenated water become anaerobic (oxygen deprived) and encourage pathogenic species of bacteria like Aeromonas and Pseudomonas to proliferate inside the waterfall filter and eventually in the pond. This can result in sick, diseased, and/or dying fish.
This is why fish disease is relatively high in typical water garden ponds compared to traditional koi ponds. Koi pond filters are back-flushable, typical "Pad-&-Media-Bag" style waterfall filters are not. All Hydro Vortex™ waterfall filters come standard with a bottom drain for backwashing and easy water changes.
Compare Cleaning a Marlin Hydro Vortex™
Medium Waterfall Filter
with Cleaning Typical Waterfall Filter Boxes
Ordinary medium waterfall filters use filter pads inside them. They also require you to purchase additional media such as lava rock to aid in filtration and to hold the filter pads in place. When researching medium waterfall filters - take note of what type of media comes with it - and it you're required to purchase additional media.
Just look at how you will have to clean the filter pads! You will have to pull them out of the filter and use high pressure water to clean them. They will be heavy and very smelly! But first you will have to remove the even heavier dirty bags of lava rock!

The TRUTH About "Annually Cleaned" Waterfall Filters
Top of Page
Common Waterfall Filter Boxes
with Filter Pads and Media Nets
Must be Dismantled BY HAND
for Annual Cleaning!
Why is Keeping a Waterfall Filter Clean So Important?
A waterfall filter is just that …. a filter.
(Roll your mouse over, or click this photo)
Think about filters for a moment:
Any type of filter, whether it be for liquids or gasses performs at its peak efficiency when kept clean – waterfall filters are no different. What would happen to your clothes if you didn’t routinely clean the dryer’s lint trap? What would happen to your engine if you didn’t change the oil filter? What would the swimming pool look (or smell) like if you cleaned the pool filter once per year? How would your water or coffee taste if you used the same filter for an entire year?
Everyone knows that filters either need to be kept clean or replaced to work effectively – pure and simple. You should RUN – not walk – away from any typical bio fall type waterfall filter that boasts that it only requires "annual cleaning". Let us explain.
So what collects in a waterfall filter anyway? The answer is fish waste, mulm and detritus (waste produced by bacterial colonies), small organic particles, algae, dissolved organic matter, and whatever passes through the pond skimmer or other pre-filter. All this “stuff” is commonly referred to as “sludge”.
Take a good look at this photo of the inside of a actual Aquascape Biofalls waterfall filter. This is sludge. The filter pads and media nets filled with lava rock are completely saturated with sludge.
When sludge is allowed to build up inside a typical bio fall type waterfall filter, the filter media becomes clogged and water will channel around it. Water channeling around the filter media is no longer being filtered. If a filter no longer filters …. then what good is it?
Once the pond filter media is saturated as seen in this photo, the sludge breaks off and finds its way to the bottom of your pond or pondless waterfall where it adversely affects water quality and dramatically promotes algae growth. Additionally, areas within a sludge filled waterfall filter that no longer have water passing through them become stagnant and oxygen-deprived.
Pathogenic species of bacteria such as Aeromonas and Pseudomonas proliferate in oxygen-deprived pond filter media and eventually pass into the pond. These pathogenic bacteria can attack your fish causing ulcers, open sores, mouth rot, fin rot, disease, and death.
This is why backwashing your pond filter
is so important!!!!
Don’t be misled by claims that the typical biological bio fall type waterfall filter only requires annual cleaning. The health of your fish may be at stake, as well as the appearance of your pond.
Think about “annually cleaning” a waterfall filter for a moment. Can it be done? Yes. Should it be done? Heck NO!!! You could mow your lawn once a year. Would you do it? Heck NO!!! Your neighbors wouldn’t appreciate your unsightly lawn for 51 weeks per year. It will be a huge time consuming and difficult chore when you do decide to mow it!
What would happen if you “annually” flushed your toilet? The conventional bio fall type waterfall filter that boasts “annual cleaning” is not providing you with the most accurate information.
A saturated waterfall filter encourages excessive algae growth as well as Aeromonas and Pseudomonas pathogenic bacteria proliferation. The algae is extremely ugly, and the pathogenic bacteria are a real danger to your koi and pond fish.
The Problems with Typical Conventional Waterfall Filters
With over 25 years’ experience installing, servicing and seeing the problems with virtually every brand of waterfall filter, company CEO, John Russell invented and patented the Hydro Vortex™ professional backwashable waterfall filter.
His goal: to resolve these common problems with unique design features, efficient function, and ease of cleaning in mind. John studied every waterfall filter available and compared them to koi pond filters - where koi and fish health is the primary concern. He discovered that all koi pond filters have the ability to be periodically backwashed to remove the unwanted fish waste, detritus, and mulm. There wasn’t a waterfall filter, or pondless waterfall filter that had this ability, and as a result, many pond and pondless waterfall owners were experiencing problems with fish health and excessive algae growth.
The Discovery:
Conventional Bio Fall Type Waterfall Filters
Utilize Media Nets Filled With Lava Rock
As Half Of Its Bio Media
Media nets filled with lava rock or other bio media can only be cleaned by removing them from the filter by hand and rinsing them with high pressure water.
Typical Conventional Bio Fall Type Waterfall Filters
Utilize Filter Pads As Half Of Its Bio Media
Filter pads can only be cleaned by removing them from the filter by hand
and rinsing them with high pressure water. (Roll your mouse over the photo to the right)
High water pressure cleaning harms the beneficial bacteria that was living on the filter pads, thus requiring completely starting the bio filter ecosystem again from scratch after every cleaning. This is a big reason why the manufacturers of these types of the conventional bio fall waterfall filters state the their filters only require “annual cleaning” as cleaning the filter pads with high pressure water – the only way possible – destroys the ecosystem of the bio filter.
The typical conventional waterfall filter doesn’t possess a vortex water motion or settlement chamber inside the filter body – there is no pre-bio stage solids separation as with the Hydro Vortex™. All the particulates that can get past a pond skimmer - fish waste, mulm, and detritus are forced to collect on the filter pads and media nets.
Once the bio media is saturated, the water flow channels around the filter media and is returned to the pond unfiltered. Additionally, the filter pads, lava rock, and other common types of filter media inside typical conventional waterfall filters are too dense to rinse with low pressure water. The filter pads, lava rock, or other bio media must be removed from the typical waterfall filter for hand cleaning.
This is why the ecosystem crashes after an annual pond cleaning. High pressure cleaning eliminates of all the good bacteria while you are trying to get rid of the bad. Look at the closeup photos on the left: how efficient do the filter pad and lava rock look to you? Does leaving this inside your filter for an entire year seem right to you? We didn't think so!
Another thing about leaving this inside your filter for an entire year: It's obvious that these filter pads and lava rock can't hold onto any more mulm. Where do you think it goes? Yup, you guessed it .... right back into your pond or pondless waterfall reservoir basin. Guess what it will then do. You're getting it now! Grow algae and cause fish disease!
All typical bio fall type waterfall filters can only be cleaned by hand! When doing your research on which waterfall filter to purchase – you need to ALWAYS ASK:
How Do I Clean
This Waterfall Filter?
There are many manufacturers of these types of typical bio fall waterfall filters: Aquascape, Easy Pro, Atlantic, Pond Builder, Pro Line, Savio, and others. They are commonly referred to as bio falls, puri falls, aqua falls, fast falls, filter falls, cascade falls, elite falls, and many other names.
It doesn’t matter the manufacturer – they may look different on the outside, but inside – where it really matters – they are all the same! Filter pads and media nets are not backwashable, and must be disassembled for cleaning.
This is a copy of anactual manufacturer's owner's manual - they are making our point for us.
As the old sayings go: "You Get What You Pay For" and "Buyer Beware!"
You can do an internet search and find a ton of information about how to clean a typical bio fall type waterfall filter. They all talk about cleaning the filter pads and the lava rock contained in the media nets once per year …. but what they don’t show is …. what you’re actually cleaning – or how you will be doing it!
This is How to Clean a Typcial Bio Fall Type Waterfall Filter
The first step is to drain the conventional bio fall type waterfall filter
Most likely the filter doesn’t have a drain unless you paid extra for a drain kit - so you’ll have to disconnect the pump and have the dirty filter water backflow into the pond skimmer and pond. Careful, it will be under pressure and can get all over you. Or purchase a second pump and hose to pump it out. Again, additional costs to the original purchase price!
The second step is to remove the media nets
These are usually filled with lava rock, but they can also be filled with bio balls or other form of bio media. Lava rock is the most commonly used media in these nets because the lava rock is heavy and holds the filter pads down inside the conventional bio fall type waterfall filter.
These saturated media nets can be very heavy – so be careful lifting them out. Small waterfall filters may have only one such media net, but the average size filter contain two or three. Larger waterfall filters contain six or more media nets.
This is what you’ll be cleaning from the media nets. As stated earlier, this is “sludge” consisting of all sorts of smelly decaying things. Make sure to wear protective clothing and gloves when handling saturated bio media. Infections are common problems associated with cleaning a conventional bio fall type waterfall filter.
Look at this lava rock. It has been in this conventional bio fall type waterfall filter for an entire year!
In the words of Howard Hughes: “Does that look clean to you?”. The pores in the lava are completely filled with sludge. The only way to clean this is with high pressure washing. It is widely understood that using high pressure water to clean bio media destroys the beneficial bacteria living on it. This destroys the pond filter’s ability to perform its primary job of bio reaction.
The next step is to remove the filter pads
They too can be heavy. The typical conventional bio fall type waterfall filter contains two to three of these saturated filter pads. Again, it is recommended to use long sleeve rubber gloves and eye protection when handling sludge saturated filter pads.
These filter pads have been in this conventional bio fall type waterfall filter for an entire year! How effective do YOU think they can be when they’re clearly saturated with sludge?
Filter pads saturated with sludge promote harmful pathogenic bacteria to proliferate and provide a huge food source for algae!
No "ifs, ands, or buts"! We've been in this industry for a long time and know what we're talking about. How do you think we get all these photos? Our service crews are booked solid from people paying us their hard-earned money to clean their ponds and filters! We photograph the jobs. If only they had all this information BEFORE they bought one of these types of filters - or hired a contractor to install one!
The next step is to high pressure rinse the filter pads and lava rock
This can get very messy! For your safety make sure to wear rubber rain gear, long sleeve rubber gloves, and protective eye-wear. Make sure to keep your mouth closed!
When high pressure rinsing the completely sludge-saturated filter pads - make sure you use enough water pressure to clean the pad, but not so much that you disintegrate it! Filter pads are expensive to replace!
The Next Step is to Clean the Inside of the Waterfall Filter Itself
The typical conventional bio fall type waterfall filter does not have a drain which makes this process very difficult. Wipe and rinse the sludge and muck from the walls of the filter and pump, or shop-vac out the slurry. If you paid extra for a drain, then rinse the sludge and muck out the drain. You'll also have to shop-vac the remaining slurry that is below the drain (since the drain isn’t really a drain but a reversed inlet on the side of the filter – and above the bottom).
Any guesses as to what this smells like?
The next step is to catch and relocate all your fish
then drain and clean the pond bottom
This is the costliest part of the “annual clean-out” or “spring-cleaning”. You’ll need a net to catch the fish, a tank large enough to hold them all, a net large enough to cover the tank so your fish don’t jump out, and an aeration system for the tank to provide oxygen to your fish.
You also need a dirty water trash pump and enough hose to discharge the dirty water somewhere – make sure to not flood a neighbor’s yard! Also, in most communities it is unlawful to dump this dirty water into the storm drains. Check with your local Authorities first - or you could be subject to a large fine.
You’ll be pumping out ALL the pond water, pressure washing the entire pond, waterfalls, stream (if you have one), and then re-filling the entire pond with fresh water. Depending on the size of your pond, the water bill can be quite high. Or, you can pay a professional who already owns the required equipment a lot of money to do it for you. You must factor in this large annual cost when you’re contemplating which waterfall filter to purchase.
All the additional costs can run you several hundreds of dollars. Oh by the way, if you don't own a pressure washer - add the rental cost to the price of the typical conventional bio fall type waterfall filter. After adding all these additional costs to the price of a typical conventional bio fall type waterfall filter, that cheap price isn't looking so cheap now is it? Again, "You get what you pay for!" Are you beginning to understand how and why a Hydro Vortex™ waterfall filter lowers your cost of ownership?
A typical conventional bio fall waterfall filter - be it bio falls, aqua falls, filter falls, or the many other terms used to describe these types of the hard to clean waterfall filters ALL state they only require "annual-cleaning". These waterfall filters get clogged with sludge and then pass sludge to the pond where it settles to the bottom. This requires the pond to be completely drained and cleaned every year at a large annual expense. Ponds with these types of bio filters experience excessive algae growth, become unsightly very quickly, and create non-ideal living conditions for koi, pond fish, and other aquatic life.
If "a picture is worth a thousand words", then how many words do all our photos tell you? You can CLEARLY see that these photos are NOT doctored in any way.
As mentioned earlier, our service division gets booked months in advance to clean ponds and pondless waterfalls that are filtered with these types of waterfall filters. This is also why we get booked for so many Ectomies!
What are People Doing with their "Annually Cleaned"
Conventional Bio Fall Type Waterfall Filter?
People are ripping them out in record numbers all across the country!
This process is known as a “Filter-Ectomy”. A Filter-Ectomy is the replacement of the conventional non-backwashable bio fall type waterfall filter with a completely backflushable Hydro Vortex™ waterfall filter.
When people get tired of their hard to clean conventional bio fall type waterfall filter – the algae, sick fish, and headaches associated with them – they replace them with Hydro Vortex™. We get lots of plastic to recycle every year!
If you’re considering purchasing a conventional bio fall type typical waterfall filter – no matter the brand – you have to add the cost of annual cleaning and the eventual filter-ectomy to the price of that filter.
If you purchase a waterfall filter solely on price alone, you will end up paying a lot more in the future. The conventional bio fall type waterfall filter has a much higher cost of ownership than Hydro Vortex™ backwashable waterfall filter.
Do Yourself a Favor,
Pay a Little More for a Hydro Vortex™ Waterfall Filter
So You Can SAVE Thousands of Dollars Over Time.
The solution to the conventional "annually cleaned" waterfall filter is the patented backwashable Hydro Vortex™. With the patented Hydro Vortex™ fully backwashable waterfall filter, you can routinely rinse the filter free of mulm and detritus before it can become sludge. Keeping the filter clean on a routine basis will prevent it from passing sludge to the pond so the pond will remain much more clean.
With a Hydro Vortex™ backwashable waterfall filter, you can routinely clean the pond bottom with a garden hose leaving the pond full of water and your fish swimming around in it. Simply use a garden hose to “fluff” any debris that has settled to the pond bottom. The water will temporarily cloud up. Your pump will pass the cloudy water to the Hydro Vortex™ filter where the filter’s vortex and the Hydro FilterSilk™ media will clean the water. Then simply perform a backwash of the Hydro Vortex™ filter. You can have a clean pond all year round without having to catch and remove your fish, drain the pond, or disassemble the filter for cleaning.
A clean pond is a healthy pond for your koi, pond fish, turtles, and the wildlife that visit the pond. In addition, a clean pond has much less algae than a dirty pond. It is just common sense.
