Aquaclear A1371 30-Gallon Biomax, 65g (2.3OZ) , White

These are amazing for beneficial bacteria and work very well!

Perfect

I started my AquaClear 30 on these bio rings. I used them for a year with a goldfish and the water read a constant 0 ammonia, 0 nitrite and 10 nitrate so I know that they did a good job keeping my nitrogen cycle healthy and strong. I did slowly start to switch over to Seachem Matrix because that's what I use in my other tank's canister filter and I had some left over. There was nothing wrong with these bio rings. They are small enough for the AquaClear 30 that I used them in and they did work well. If this review was helpful to you in any way, please let me know by clicking on helpful. Thanks

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!

Not the subjected filter but it still works. I wanted to try the biological filtration so I bought the small pack for a 30 gallon and tried it in my corner filter. It seems to be working well and it was very good price.

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!
