AquaClear 20 Foam Filter Inserts are replacement filter media for the AquaClear 20 Power Filter. The AquaClear 20 Foam Filter Insert is a mechanical filter media that effectively removes particles and debris from aquarium water. It also prevents particulate waste from prematurely clogging other media in the filter. Primarily a mechanical filtration media, it also provides powerful biological filtration as friendly bacteria eventually grow inside its pore structure. Exclusively designed for the AquaClear 20 Power Filter, the Foam Inserts are safe for fresh and saltwater aquariums. AquaClear creates a wide variety of products for freshwater tanks such as fish tank accessories, fish tank decorations, and aquarium filter media that is perfect for large and small fish tanks.

I use these for 30 days and then rinse out before I put in a new sponge. I think it really helps to keep my tank clean.

I waited for a little while before writing that it worked great. I’m very happy with this filter. I’m always happy with the things that this manufacturer makes.

My fish love this! Just kidding. It is a pack of foam inserts ready for tank cleaning day. The 3-pach here is a great value.

[Update January 2025: This foam sponge has proven to be very useful over time. I would recommend owning some in reserve, because it has multiple aquarium uses. I've used it as I said in my old review below, I use it to clean algae off the glass, I've used it to cover a sharp edge on an air stone, and now I've used it to make an emergency sponge filter. I'm going to order more (it's out of stock, so I'll order a different size from the same brand I guess), since I've gotten a lot of use out of it! It is durable and easy to use.]Old review, June 2022:I bought these to slow down my filter to be safer for my shrimp!I cut a hole in a chunk of one of these sponges and slid it over the intake tube of my filter, so baby shrimp won't get sucked in through the holes. It's ugly because you can see the dirt on the white sponge, but functionality is what I was more concerned about. I also wedged another chunk over the output of my filter to distribute the flow more slowly so there is less of a current, so my shrimp can swim without being propelled into the wall.This sponge has pores that are kind of wide, but still make my filter safer, and I still have extra. It doesn't affect the filter's ability. (For reference I'm using a Tetra brand Whisper filter.)

I wanted to install this with my Aqua Tech hanging back filter which is a 3 stage filtration. However, the filter is too thick in which I cut it in half so I had room for my other filter pad and biological ceramic bag. Not a big deal if you have a bigger filter. It does the job and that's what makes the fish happy. So far I would recommend this filter foam.

I purchased this to use in my HOB filters rather than the expensive cartridges that they suggest buying. I didn’t want carbon in my tanks and this filter sponge works well and fit in my filters after I cut them to my preferred size. I used these with filters other than the one it’s intended to be used with. I also put this in my hospital tank to help with filtration. Overall, this is very versatile.

This filter media is great! I bought my first pack from a local fish store a few months ago, and now that it's time to swap it out, I've decided to stick with the same brand. Buying it in multi-packs here is way cheaper than any LFS!I had this brand recommended to me to use in my Azoo Mignon 60 filter, and though I do need to cut the foam a bit to fit inside, I still couldn't be happier with it. It does the job wonderfully! I would definitely recommend this media even if you don't use Aqua Clear filters.You can even see the good bacteria cultures forming on it- that tan/gold stuff that builds up over time isn't just tank waste. However, in order to enjoy the full benefit of a bacteria culture in your filter, pair the sponge with Aqua Clear's Biomax!I believe the Aqua Clear brand was recently acquired by Fluval. I have seen new packaging with the Fluval logo claiming it is the same thing as the Aqua Clear, so if you can't pick this up online but see the Fluval stuff in your LFS, it's -probably- the same thing.
