Questions & Answers

6 Customer Questions

Could I use this for my Aqueon Quietflow 10 Gallon filter?

Answer by Chewy • Sep 02, 2019
This sponge is intended for use with Edge aquarium kits and the Fluval Edge filter.

What are the dimensions of the filter?

Answer by Chewy • Apr 11, 2024
This filter measures approximately 3.75 inches long by 1.5 inches in diameter.

Does the hole go all the way through the sponge?

Answer by Chewy • Sep 17, 2024
The hole does not go all the way through the sponge.

Can it work on the 110 gallon flu valve hang on back filter

Answer by Chewy • Apr 21, 2021
The pre filter sponge will stretch slightly, however the intake on the AQ110 is a bit thicker so it may be a tight fit.

disappointing, but my own fault

I thought I was ordering a prefilter. This is really, but the sponge is too dense, it only slows the filter down.

Ever since I had a betta get curious and sucked up into a filter, I use these on the intake of all my filters to keep a small fish from being sucked up into the filter. FYI: the betta did survive the ordeal, but it was very touch and go for awhile.

Perfect size and function

Smaller than anticipated, but surprisingly fit perfectly and works better than a larger sponge.

I got this because I’ve had problems in the past with fish’s tails being sucked into the filter and tearing them apart. This is a great preventative
