- Three filtration stages in one compact unit
- Choose rainfall, bubbles or directed water flow
- Adjust the flow to suit your aquarium
- Detach the chambers for easier routine cleaning
Which size should I choose?
Choose 8W for the listed 2–13 gallon range, 9W for 13–35 gallons or 15W for 35–45 gallons. Check the dimensions below against your available tank space. Stocking level and the flow your animals need also matter; tank volume is a starting guide.
What does the filter do?
Water passes through sponge, activated carbon and biological media. Sponge traps debris, carbon helps address odors and discoloration, and biological media provides a surface for beneficial bacteria. The outlet circulates the filtered water back into your tank.
Can I adjust the water flow?
Yes. Adjust the flow and use the supplied outlet attachments for rainfall, aeration or directed circulation. Keep the air inlet above the water when using the aeration setup and follow the included assembly instructions.
How do I clean it?
Unplug before servicing. Detach the chambers and rinse reusable sponge and biological media gently in removed aquarium water when needed. Follow the supplied instructions for carbon replacement and impeller care. The filter does not replace water changes or water testing.

Start with a setting appropriate for your livestock, then observe and adjust. Follow the supplied instructions for each outlet setup and water level.
A fit for your setup
Start with your tank.
Choose your size.
Compare the listed tank range, flow and body dimensions before choosing your option.
| Size | Listed tank range | Rated flow | L × W × H |

Does this replace water changes?
No. Keep an appropriate water-change and testing routine. Clear-looking water alone does not confirm safe ammonia, nitrite or nitrate levels.
Is it suitable for delicate fish or shrimp?
Suitability depends on the animal, intake openings, flow setting and tank setup. Do not assume every size is suitable for fry, shrimp or delicate species. Check their needs before choosing.
How is it powered?
The supplied specifications show DC 5V USB power with an adapter. Follow the included power and installation instructions. Keep electrical connections dry, unplug before maintenance and never run the pump dry.
