Ahi Series™ Small Pondless Waterfall with 5' Stream Kit
Create a stunning, low-maintenance backyard water feature with the Ahi Series™ small pondless waterfall kit. This compact system features a 16" wide cascading waterfall flowing downward approximately 18" into a 2' × 5' stream or babbling brook, before disappearing through the advanced HydroSieve™ pre-filter into the underground HydroChamber™ water storage system.
The best pondless waterfall kits are designed for easy cleaning and long-term performance. That's exactly what you get with the Ahi Series™.
- ✔ No gravel pits
- ✔ No messy cleanouts
- ✔ No hidden maintenance problems
Just clean, clear, beautiful water — made simple.
Why This Small Pondless Waterfall Kit Is Different
Unlike traditional pondless waterfall kits, the Ahi Series HydroPure™ Filtered Pondless System includes:
- HydroSieve™ Pre-Filter - Captures debris for easy routine removal
- HydroChamber™ System - Combination pump vault + water storage in one compact unit
- Ahi Hydro Vortex Backwashable Filter - Patented design removes dissolved organics and fine particulates
Most "standard" kits rely on rock and gravel covered basins that trap debris and are extremely difficult to clean.
👉 The truth?
They can only be cleaned by hand - if at all.
No Gravel Basins. No Maintenance Headaches.
Traditional pondless waterfall systems use rock and gravel to filter debris - but:
- Debris gets buried deep in the gravel
- Organic matter breaks down into sludge
- Water turns brown or green and smells terrible
- Algae growth increase rapidly
And cleaning it? Nearly impossible.
HydroPure™ Filtered Pond Systems eliminate this problem entirely.
All pondless waterfalls collect:
- Dust and pollen
- Bird waste and feathers
- Animal hair and dander
- Leaves, blossoms, and organic debris
- Airborne pollutants and phosphates
If you have a pondless waterfall without both a pre-filter and a waterfall filter, what do you think happens to all this windblown debris?
Without proper filtration, debris remains in the system to rot, decay, feed algae, and degrade water quality.
That’s why every kit includes both a Hydro Vortex™ Waterfall Filter and HydroSieve™ Pre-Filter:
Advanced Filtration = Cleaner Water, and Less Algae
- Captures windblown debris for easy routine removal
- Traps fine particulates for easy routine removal
- Processes dissolved organics
- Improves water clarity and odor
- Polishes the water for maximum sparkle
- Reduces algae growth
Modular Design = Unlimited Installation Flexibility
The Ahi Series HydroPure™ Filtered Pondless System gives you complete creative control.
Install components:
- Together
- Or remotely in separate locations
✔ Place your HydroChamber™ water storage tank anywhere
✔ Hide your HydroSieve™ pre-filter out of sight
✔ Connects easily with standard 4" pipe
No other brand of pondless waterfall kit offers this level of flexibility.
HydroPure™ Filtered Pondless Systems = More Design Options. More Creative Freedom.
With modular installation, you can:
- Build waterfalls in one area
- Locate the pre-filter away from the pool
- Locate the water storage tank near existing electrical or water supply outlets
- Integrate landscaping, patios, and hardscapes in between
Design without limitations.
Easy to Clean = Lower Ownership Cost
Hard to Clean = Higher Ownership Cost
Before buying any brand of pondless waterfall kit, for your own peace of mind - ALWAYS ASK: 👉 “How do I clean it?”
With common rock and gravel basin pondless waterfall systems:
- You'll spend hours trying to hand clean the gravel
- Or pay for expensive annual draining and pressure washing
With the Ahi Series HydroPure™ Filtered Pondless System:
- Debris is captured and easily removed
- Patented waterfall filter is backwashable
- Less digging - easier to install
- No mess
- No stress
- Lower cost of ownership
A clean system is a beautiful system.
Save Money with a Smarter System
The HydroChamber™ all-in-one system replaces:
- Two slotted pump vaults
- Two matrix blocks
- Basin underlayment
- Basin liner
- Basin rock and gravel
This means:
- Smaller excavation
- Faster installation
- Less labor
- Less materials
- Lower overall cost
Why dig a bigger hole than you need to?
Common rock, gravel, and matrix block based pondless kits found everywhere online lead to:
- Sludge buildup
- Brown or green foul-smelling water
- Difficult or impossible cleaning
- Poor water quality for pets and wildlife
- Expensive annual cleanings that require repeated draining and pressure washing
There's a reason most manufacturers don't explain how to clean their systems.
👉 Because you can’t.

Ahi Series HydroPure™ Filtered Pondless System
✔ Easy to install
✔ Easy to clean

✔ Crystal-clear water

Benefits of an Ahi Series Pondless Waterfall Kit
The Ahi Series™ HydroPure™ Filter Pond Systems are engineered for maximum design flexibility, easy maintenance, and cleaner water - something conventional systems simply can't match.
The Ahi Series HydroPure™ Filtered Pondless System delivers unmatched flexibility, cleaner water, and easier maintenance - without the hassles of traditional rock and gravel based systems.
Unlimited Design Flexibility with Modular Components
Design your waterfall your way.
With fully modular components, you can install each part exactly where it works best:
- Place the Ahi Hydro Vortex™ filter facing your patio or focal point
- Install the HydroSieve™ pre-filter in a hidden or convenient location
- Position the HydroChamber™ water reservoir near your power source
Or, install everything together - it's completely up to you.
No other small pondless waterfall kit offers this level of flexibility.
Why Conventional Pondless Waterfall Kits Fall Short
Most pondless waterfall kits - regardless of the brand - use the same outdated system:
- A waterfall spillway that is not a filter of any kind
- A slotted pump vault with or without matrix blocks
- Underlayment, and rubber liner
- Lots of rock and gravel
- Fixed design (basin must always be under the waterfall or stream)
- Difficult or impossible to keep clean and free of debris
- Lack of filtration promotes algae growth
- Dirty brown/green smelly water
Common Problems with Rock and Gravel Based Pondless Waterfall Systems
Traditional rock and gravel based systems:
- Trap debris in the gravel
- Cannot be easily cleaned
- Lead to algae, odors, and unhealthy water conditions
Rock and gravel basins trap leaves and debris, they rot over time, and then feed algae - creating odor, discoloration,
and ongoing maintenance problems.
A Smarter System:
How the Ahi Series HydroPure™ Filtered Pondless System Works
The Ahi Series HydroPure™ Filtered Pondless System uses a closed-loop, high-efficiency filtration system:
- Water is pumped from the HydroChamber™
- It enters the patented Ahi Hydro Vortex™ backwashable waterfall filter
- Water rises up through the Hydro FilterSilk™ bio media, removing dissolved organics and trapping fine particulates
- Clean water flows out of the top of the Ahi Hydro Vortex™ filter and over the waterfall
- Water flows into the HydroSieve™ pre-filter capturing leaves and debris for easy removal
- Water then flows from the HydroSieve™ pre-filter back to the HydroChamber™.
When the System is OFF
- Water is safely stored underground inside the HydroChamber™
- No standing water is visible
- Safer for children, pets, and wildlife
Ahi Series HydroPure™ Filtered Pondless System Solution
- HydroSieve™ pre-filter captures debris for easy removal
- Hydro Vortex™ filter processes dissolved organics
- Backwashable system makes cleaning fast and simple
Result: Clean, clear, fresh water - without the headaches.
Hydro Vortex™ Filter Simple Backwashing Options
Manual Backwash
- Turn off pump
- Open the Ahi Hydro Vortex™ filter's drain valve and let it completely drain
- Rinse the Hydro Vortex filter from the top down with a garden hose (no need to disassemble the filter for rinsing - as the media rinses in place)
- When water exiting the drain valve runs clear, the filter is clean
- Close the drain valve
- Re-start the pump
HydroFlush™ Self-Cleaning Backwash System

HydroPure™ Filtered Pondless Systems Create
The Ultimate Pondless Waterfalls that are
EASY to CLEAN!
1. Keep your pump running and use an ordinary garden hose to rinse leaves, debris, and fine particulates downstream from the waterfalls and/or stream into the Hydro Sieve™ pre-filter for easy removal.
No need to remove the pump when cleaning and maintaining a HydroPure™ Filtered Pondless System. Removing the pump is only necessary for winterizing the pondless waterfall.
2. Turn off your pump and remove the stainless steel filter basket from the Hydro Sieve™ pre-filter.
Open the Hydro Sieve™ pre-filter by lifting off the lid to expose the internal stainless steel filter basket.
Grab the handle which is well above the water line to remove the basket. Empty the basket, hose it out, and then put it back inside the Hydro Sieve™ pre-filter.
3. Open the drain valve at the bottom and backside of the Hydro Vortex™ waterfall filter and let it completely drain. You will notice dirty water draining from the Hydro Vortex™ waterfall filter.
Every model of Hydro Vortex™ waterfall filter comes complete with a drain, drain pipe, and a drain valve for easy cleaning and backwashing.
4. Backwash the Hydro Vortex™ waterfall filter either manually, or with the HydroFlush™ Backwash System.
Manual Backwash: Using an ordinary garden hose, rinse the Hydro Vortex™ waterfall filter from top down with fresh water. No need to disassemble a Hydro Vortex™ filter for cleaning.
Rinse water through the Hydro FilterSilk™ bio media inside the Hydro Vortex™ waterfall filter until the water flowing out the drain runs clear. When the water runs clear, the filter and bio media are clean. Close the drain valve and restart your pump and waterfalls.
HydroFlush™ Backwash System: With the filter's drain valve open, turn the HydroFlush™ valve to the "Backwash" position. Turn on the pump to send water through the froth-port at the top of the Hydro Vortex™ filter. The water will shoot upwards and then fall back down onto, into, and through the Hydro FilterSilk™ media inside the Hydro Vortex™ waterfall filter. When the water exiting the drain at the bottom of the filter runs clear, the filter and bio media are clean. Close the drain valve, and turn the HydroFlush™ valve back to the "Filter" position.
5. When water exiting the Hydro Vortex™ waterfall filter's drain is clear, the filter and bio media are clean. Close the drain valve.
6. Turn on your pump and enjoy your clean and pristine pondless waterfalls.
If you opted for an automatic water fill float-valve, the valve will automatically re-fill the pondless waterfall inside the Hydro Chamber™ for you. Or, you can add water with a garden hose to replace the small amount of water that was used to backwash the Hydro Vortex™ waterfall filter.
That's it! You're done!
No fuss, and no mess.
Super easy, super quick.
The Easy to Clean Pondless Waterfall
HydroPure™ Filtered Pondless Systems are the absolute easiest to clean pondless waterfalls - period. Compare for yourself before purchasing any brand of pondless waterfall kit or having one installed for you by a contractor.
