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

Answer by ChewySep 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 ChewyApr 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 ChewySep 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 ChewyApr 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.

Helps keep main filters clean

Not only does this pre filter help keep the main filters clean but also keeps tiny fish and other small creatures from being sucked up into the filter system.

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.
