What kind of filters does this use?

Answer by ChewyAug 28, 2024
This product includes the Marina Power Filter and will require Marina filter cartridges to run smoothly. The cartridges are sold separately on our site.

will that work for a ten gallon tank my other filters are not cleaning the tank

Answer by ChewyJul 19, 2018
Each size will work in a 10 gallon tank. The S10 holds up to 10 gallons, the S15 holds up to 15 gallons, and the S20 holds up to 20 gallons. The Marina Power Filter is also equipped with an adjustable flow control and includes a strainer sponge to keep smaller fish from being pulled into the filter.

How long and how wide is this filter? The dimensions are sketchy about which is height and which is width.

Answer by ChewyJul 17, 2018
The S10 filter measures 7.3 inches long x 6.5 inches wide x 3.7 inches high. The S15 filter measures 9.1 inches long x 6.4 inches wide x 3.7 inches high. The S20 filter measures 11.5 inches long x 6.4 inches wide x 3.8 inches high.

How do you adjust the water flow on the filter of this model?

Answer by ChewyDec 10, 2019
When lifting up this power filter's cover, the flow control valve is located on top of the tubing outside of the water.

I have a s10 of the filter in my 6 gallon. I bought this s20 for my 10 gallon. It’s quiet and keeps the tank very clean. Self priming is a definite plus! I use my own media in some of the channels instead of all disposable filters. Keeps my BB. The waterfall outflow is nice.

All around best HOF

A sleak design, basically no noise, huge space for media. At first I wasn’t really sure about it because it looked like it was missing parts, I only had to connect

A sleak design, basically no noise, huge space for media. At first I wasn’t really sure about it because it looked like it was missing parts, I only had to connect 3 parts basically. After I turned it on, it all made sense. Truly a game changer for me, never using another one

A picture or illustration of entire filter on aquarium would have helped a lot with setup.

My go to filter, I own 6 of these. Slim, no hulking bulk sticking out from aquarium. Also love that the pump itself is in the aquarium water - no priming, doesn't run dry if the power goes out.

Sounds like it’s full of gravel now, super finicky

It worked great at first, except I had to wedge paper towels in a bunch of spots to prevent it from being noisy if it rattles against the tank. Now it sounds like

It worked great at first, except I had to wedge paper towels in a bunch of spots to prevent it from being noisy if it rattles against the tank. Now it sounds like it’s full of gravel, I was hoping my regular maintenance routine would clear that up but it sounds even worse now
