AquaClear 20 BioMax, Aquarium Filter Replacement Media, A1370A1

These were perfect for my fish tank. I chose these because they are significantly cheaper than buying singles at a chain pet store. Worked perfectly, and I would highly recommend.

I have a 20 gal aquarium. I use aqua clear products, I purchase them through Amazon, they arrive quickly, they are a great price from this company and really do a good job Thank you!

Great at filtering the water. I thought it would let all the particles slide, but I immediately noticed a difference in my aquarium's transparency. With a high pressure water spray you would be able to dislodge a majority of the dirt and grime, so I was able to extend its life quite a bit. Super happy with it's value for quality.

What else to say, it is biomax for your filter.

Everything was okay.

I bought this to add some biofiltration to an AZOO Mignon 60 filter. That filter is very tiny without much space for filter media. This Aquaclear Biomax is actually too big to fit in the Mignon filter, however, the mesh bag that holds the bio media is easy to cut open, so I just added the bio media to a smaller mesh bag. The bio media itself is great. Very small cylindrical shaped ceramic pieces with a large surface area to encourage beneficial bacteria growth. The small size of the individual pieces makes this ideal for any small filter.

This product is a little bit for a 20 GALLON TANK. I purchased it for my 5 gallon system but I also have bio balls as well to help with the bacteria load. If you are considering this for a tank, then it is OK, but remember the more surface areas there are the better it is, so get about three or four boxes for a larger tank. For my 5 gallon planted system that I am creating I am using this plus two bags of bioballs as well as a lot of bacteria. I am also using seiryu rocks in my tank so there would have bacteria growing on that as well. Use fluval biological booster to help cycle your tank. This product in large numbers comes with strength, so get enough.

We've had our Fluval Edge 6 Gallon system for over a year now. When It was time to replace the Filter Media, our local pet store no longer carried the Edge line replacements. Knowing Fluval and AquaClear are owned by the same parent company, I found out the Edge filter was a re-branded copy of the AquaClear 20 filter. I confirmed this info by checking out a few aquarium hobbyist blogs. I ordered each of the replacement filter medias (sponge, carbon & biomax) and can confirm they are an exact match for the Fluval Edge stock filter basket. Pricing was better on Amazon than other online aquarium suppliers I checked. I had no local retail store to compare prices with either so Amazon deservedly received my business.

Very useful and gives good bio filtration

Alter Filter ersetzen. Passt perfekt

New design and better quality than what I recall when I used this product years ago

Muchas gracias

Utilisés dans un petit filtre sans problème, je les ai transféré dans mon nouveau filtre plus grand, en rajoutant des nouilles céramiques classiques : aucun pic, passation parfaite, et je pense que ces médias y sont pour quelque chose.
