Biohome SuperBioGravel Aquarium Filter Media (5 Pound)

I used this media with some other sizes/shapes of the same to improve my biorb filtration. It’s amazing.Biorbs are notorious for being terrible because the filtration is awful. But, I used this under my substrate and my tank has been perfect.

messbarer Erfolg - Wasser unheimlich klar !!

I use 3 Fluval 307 canister filters for my 60g. I have one 4" Flowerhorn. In each canister I fill the 3 trays with BioHome SuperBio Gravel, 6lbs in each canister... 18lbs total across the 3. I leave the sponges in the left tray for mechanical filtration. I place a thin layer poly fiber floss at the top below the intake/outtake. I'm noticing my Nitrate levels to be around 10ppm constant. For this to help control Nitrates you will need a lot of this stuff, over what is recommended on their website. Highly recommended.

This aquarium biological cintered glass media is a great value for the money. I have used this company’s other biological media products with great success. This material is special as it easily fit into the filter I used and is just great at growing both aerobic and anaerobic “good” bacteria so necessary for keeping a healthy fish and plant aquarium.

Very, very large. Would be better if it was gravel sized. Would be great for a sump, but, not a regular filter like a hob. Very large pieces some just under 2". Perfect if smaller.
