This filter serves our 20 gallon community tank and there is quite a bit of food waste. I change the filter weekly and the water stays crystal clear.
They Pull Out So Much Nasty!

I never knew my tank was that dirty but after changing the cartridge my water was much cleaner. After a week the cartridge was really nasty but after quickly rinsing it my tank was clear as before.
The best filters

We've used these filters for a while now and love them. They work well for our tank and only have to be changed once we month. Previously purchased the SAME EXACT FILETERS through a pet store chain for nearly twice the price. Thanks Chewy for having such amazing prices.
