A Waterfall Filter Designed Around the Owner
Most waterfall filters can make a beautiful waterfall. The difference becomes apparent when it's time to maintain them.
The Dolphin Hydro Vortex™ 25" Waterfall Filter provides biological filtration and fine water polishing while making routine cleaning remarkably simple.
Easy to Clean • No Filter Pads • No Routine Media Replacement • Completely Backwashable • Made in the USA
Spend More Time Enjoying Your Water Feature
Routine maintenance shouldn't mean pulling apart your waterfall filter.
The Dolphin Hydro Vortex™ can be cleaned in as little as 2 minutes without removing the Hydro FilterSilk™ bio-media.
Its settling cone and bottom drain allow accumulated material to be flushed from the filter rather than requiring you to remove dirty filter pads and media bags by hand.
With the optional HydroFlush™ Backwash System, cleaning is as simple as turning two valves.
No filter disassembly. No dirty filter pads to remove. No replacement filter pads to buy.
Completely Backwashable
Water enters the Hydro Vortex™ in a way that creates rotational flow inside the filter. Heavier material can settle toward the bottom settling cone while water continues upward through the Hydro FilterSilk™ bio-media.
During cleaning, accumulated material is discharged through the filter's bottom drain.
Every Dolphin includes the drain components needed for manual cleaning. For even easier maintenance, the optional HydroFlush™ system uses the water feature's existing pump to reverse water flow through the filter.
No separate blower or air pump is required for backwashing.
No Filter Pads to Remove or Replace
The Dolphin includes 7.32 cu. ft. of Hydro FilterSilk™ bio-media.
Unlike conventional filter pads that must be removed for thorough cleaning and eventually replaced, Hydro FilterSilk™ remains inside the filter during routine backwashing.
Its highly open structure provides both biological filtration and fine water polishing while allowing water and loosened debris to move through the media during cleaning.
The result is simple:
Install the media once. Backwash the filter when needed.
Cleaner Water Through Two Types of Filtration
The Marlin isn't simply a waterfall box.
It combines two important filtration functions:
Biological filtration provides surface area for beneficial bacteria that help process dissolved waste.
Fine water polishing captures smaller suspended particles that have already passed through the pond skimmer or pre-filter.
Pondless doesn’t mean debris-free. Even without fish, dust, pollen and fine organic particles continually enter the water. In a HydroPure™ pondless system, the HydroSieve™ pre-filter captures larger debris before the pump, while the Hydro Vortex™ provides biological filtration and fine water polishing for cleaner, clearer recirculating water.
Designed to Disappear Into the Landscape
The filter shouldn't be the first thing people notice.
The pond or pondless liner attaches directly to the face of the Dolphin Hydro Vortex™, allowing waterfall boulders, cobblestones and landscaping to surround the 25" waterfall opening.
Once installed, the filter virtually disappears.
You see the waterfall—not the filter.
Easy to Install
The Dolphin was designed with both professional installers and homeowners in mind.
The liner attaches directly to the filter face, the drain system is included, Hydro FilterSilk™ media is included, and routine installation doesn't require specialized equipment.
That means fewer additional components to purchase and a straightforward installation for DIY pond and pondless waterfall projects.
Lower Cost of Ownership
Purchase price is only part of what a waterfall filter costs to own.
The Dolphin is designed around long-lasting components and simple routine maintenance:
No replacement filter pads. No routine biological media replacement. No blower required for backwashing. Simple routine maintenance you can perform yourself.
Because the filter can be routinely backwashed, accumulated material can be removed when needed instead of being allowed to build up until a more involved cleaning becomes necessary.
One Filter. Several Ways to Build.
The Dolphin Hydro Vortex™ provides biological filtration and fine water polishing for several styles of water features.
Easy to Own Is the Real Benefit
A waterfall filter shouldn't just work well the day it's installed. It should remain practical to maintain for years afterward.
The Dolphin Hydro Vortex™ was designed to make routine maintenance simple, so caring for your water feature doesn't become a project of its own.
Spend less time maintaining your water feature and more time enjoying it.
