Fits 10 gallon tank?

Answer by Chewy • Sep 13, 2017
The 90 gph is for terrariums up to 20 gallons, while the 125 gph is for terrariums up to 55 gallons.

Does this fit my topfin filter for a 55 gallon?

Answer by Chewy • Jul 31, 2020
These filters are designed to be used with the Tetrafauna ReptoFilter for Frogs, Newts & Turtles.

How often should I change the large filter?

Answer by Chewy • Jan 13, 2026
Cartridges should be replaced every two to four weeks, dependent on how much food is fed, how often partial water changes are performed, and the stocking load of fish, reptiles, or amphibians.

what is the difference in size between the medium and the large filters?

Answer by Chewy • Oct 14, 2020
The Medium cartridge is 3.0 x 5.2 inches and the Large cartridge is 4.6 x 6.4 inches.

Easy

These filters make things so easy. They work great and you can wash them once to extend the life of them . However, I tried washing them twice and it really doesn’t

These filters make things so easy. They work great and you can wash them once to extend the life of them . However, I tried washing them twice and it really doesn’t work-the water doesn’t stay as clean.

I have been using these filters for years and years for my turtle tanks. They keep my turtle water sparkling and my turtles healthy. Easy to replace too! They last about a month or more for me. I think they are a great value.

Good Filter. Poorly Packed by Chewy.

Filters are not in a bag inside the box anymore. Boxes packed with Cat-litter/large weight items get crushed and everything inside is coated in charcoal upon opening

Filters are not in a bag inside the box anymore. Boxes packed with Cat-litter/large weight items get crushed and everything inside is coated in charcoal upon opening the package. This has happened over 5 times now. Wish they would seal them in a bag, or send seperately.

pure clear water

Glad to find these at Chewy. No longer available at our local pet store. Worked well years ago and we wanted to use this for my husband's new aquatic turtle.

Easy to use

I use these filters in my frog aquarium. If you were in a pinch, you can rinse them off and keep using them a little longer. They really help keep the aquarium
