Review on EcoBio Block EBSNC20107 Nano Water Clarifier by Brandi Walker

I have no proof of this, of course I can't ask Pisces. But barely a week later when I put them in, one of my fish was dead and the other seriously ill. They were fine for several months, I just tried to reduce the amount of green algae in the aquarium. After I put them in the tank my beta had a damaged tail and it took weeks of rehab and over $100 to replenish the bacteria, heal the fish and stabilize the plant life to fix the tank.
