Review on Poly Bio Marine APMPF 9_0200 POLYBIO Poly Filter by Jennifer Mounce

I absolutely LOVE this stuff. Even if it's in an autoship. If you have sensitive/tender fish/inversion this product is a must have. I saw it for the first time on aquarists youtube channel and I am very happy about it. I'm a very busy person, have multiple aquariums and don't always have time to do my water changes properly with a product that I know will keep my aquatic babies safe. out of the tank for a few days if you add chemicals to the tank (supplements or medication) as this will suck the cure right out of the water. It also removed the tannins from my Blackwater tank (which isn't bad, just ruins the look).
