AquaClearA1371 30-Gallon Biomax, 65g (2.3OZ) , White

Got this product to change out the filter of our fish tank. This works great in our tank. We love looking at our fish now that it’s clean and bright and sparkly. I will choose this again when I need a new filter.

I’ve been using the AquaClear BioMax Filter Inserts, and I must say, they are fantastic! These inserts, equipped with BioMax ceramic rings, have significantly improved the stability of the water in my aquarium. The intricate pore system on the BioMax surface is a haven for beneficial bacteria, which has done wonders for maintaining water quality.With these filter inserts, I’ve noticed a positive impact on the overall health and well-being of my aquatic friends. It’s evident that this product is a game-changer when it comes to creating a thriving and balanced aquatic environment. I highly recommend AquaClear BioMax Filter Inserts to all aquarium enthusiasts. They’ve certainly made a difference in my setup!

My son wanted a fish last year…well, now we have a 20 gal tank and the offspring of said fish (close to 15 platys). I was unwilling to move to a larger tank, and fortunately all fish are female, so decided to get a good filter instead. I got the Fluval 30 gal and use biomax as one of the 3 substrates. I do a partial water chance once per week and vacuum part of the gravel, but the tank never really gets dirty. I change the charcoal about every other month or so, and change this every 4 months. Great deal for a solid product.

Been using this brand for many years for caring for my turtles’ water health. Perfect for all water turtle parents!

I like the filter (that I bought here) very much. I thought it was a bit noisy at first but before I had the chance to learn how to lube the impeller, it quieted down so that it's virtually silent, much quieter than a canister across the room.Also, there is a coupon deal with the filter (my box didn't have the coupon but I found it online in the listing on a pet supply company website) where if you buy the filter and one year's supply of inserts (12 carbons, 6 foams) the company will send you enough for another year. Such a deal!

I use these In all my filter haven’t had a nitrite issue since

Great product at a great price. Works great.

Small mesh bag contains the matrix. Easy to use
