Questions & Answers

5 Customer Questions

What are the measurements of the pad?

Answer by Chewy • Feb 04, 2019
The foam insert measures 1.62 x 2.25 x 2.75 inches.

How many are in the box?

Answer by Chewy • Mar 25, 2025
This only comes with 1 filter.

Is this filter safe to use in a cat or dog water fountain?

Answer by Chewy • Oct 27, 2021
This insert is intended for use with the AquaClear aquarium filter.

How often should I replace these?

Answer by Chewy • Jan 12, 2019
While foam can be rinsed and re-used many times to ensure its effectiveness, it is strongly recommended to replace it at least twice a year. As it ages in water, it becomes increasingly difficult to rinse thoroughly and may start to wear and break down.

Just a great product or at least use to be.

I have read these have or are going to be discontinued, since Aquaclear is no longer, now it’s Fluval.

Great

Is it very good thing you can find to help your filter to help your fish tank stay healthy and tank clean and if you can’t find it there you can always find it

wrong size

We like these foam filters but these are not the right size. Can I return them? We needed the 70’s but got 20 completely my fault.

Love it what else could you ask for

Great product I use this on all my hobs! I even mod them to make them fit so I don't have to buy unnecessary stuff and helps my tank build the proper bacteria needed

Great for cat fountains

I actually bought this to replace the filter in my cat fountain. It is easy to cut down into the size I really need and does a great job of filtering out debris

Multifunctional

We use this to clean the tank glas and also in the filter. It's much to thick for our 5 gal filter but cut in half works excellent!
