Versatile
I got this 4 my aquarium. What was surprising about it is how versatile it is. It makes a wonderful non-scratch scouring sponge. It's worked well whichever way I've used it n cleaned up very well. A very affordable n valuable discovery

A Little Smaller
The product dimensions are 1.6” x 2.2” x 2.8”, and the box they come in is 1.9" x 2.4" x 3.4". So keep that in mind. It's perfect for my fish tank, and very easy to clean. I put them in a section of my under tank to clean more and they have helped a lot with keeping the tank clean. I would definitely buy these again.

Must have in your aquarium
Good for a 5 gallon planted tank. Keeps my water clear. Pair this up with the AquaClear biomax and activated carbon and you’ll be set. Definitely saves you money in the long run.

Arrived in a damaged box, may have been used
I received this item in a damaged box and possibly used by another customer. Since I can't confirm this and since the product works fine, I will leave a 4-star.

It is easy to use
Bought this as a replacement for a foam pad I had been using in an AquaClear 20 Power Filter for a long time. It is easy to use. Can use right out of the box. I just took the old foam pad and rinsed it with some aquarium water. Then I used the rinsed water from the old foam pad to soak the new foam pad in for a minute or two before putting it in the filter. That way you are getting some needed bacteria into the new pad so that you might be able to keep the aquarium from going into a new cycle or from going into a full cycle.

Hagen AquaClear 20 Foam – My Take
I’ve been using the AquaClear 20 foam in my tank for a while now, and honestly, I think it’s a super underrated part of the filtration system. It doesn’t look fancy, but it does exactly what it’s supposed to. 👍 What I like: Catches everything. This foam pulls out a surprising amount of junk from the water. Even after just a few days, it’s already loaded with debris, which shows it’s actually doing its job. Keeps water looking clean. My tank water always looks crystal clear, and I credit the foam as a big part of that. It really handles mechanical filtration well. Helps with biological filtration too. I like that it's not just for trapping gunk—the pores are perfect for beneficial bacteria to colonize, which helps keep the water chemistry stable. Reusable. I just rinse it out in tank water during maintenance and pop it back in. I’ve reused the same one a bunch of times before replacing it. Easy to use. Fits perfectly into the AquaClear 20 filter with no hassle. Doesn’t shift around or get in the way of other media like the BioMax or carbon. 👎 What’s not great: Gets dirty fast. That’s kind of the point, but if you don’t clean it regularly, it can clog up quickly and reduce flow. It’s not exactly low maintenance. Only works with AquaClear 20. If you don’t have that specific filter, this foam’s probably useless to you. Needs replacing eventually. Even with rinsing, it does break down over time. I noticed after a few months, it starts to lose its structure. My verdict: If you’re running an AquaClear 20, this foam is a no-brainer. It’s cheap, easy, and does a great job at keeping your tank clean and healthy. Just stay on top of rinsing it out, and it’ll serve you well.
