We read that this would help and boy did it. We didn't have to change a single other thing about the tank and the pH has settled at 7.4, even with the driftwood still in there. We now have two new mystery snails and they happily race around the tank nonstop - going on two months now.
I've noticed a few questions about the amount needed and how to get to a specific pH. This coral functions as a buffer, so there's not really much you can do to tweak the numbers. It will dissolve as long as the pH is below 7.4, raising it until it gets there. At a pH of 7.4 the coral stops dissolving, so there's no risk of going too high. I would recommend this as a natural, chemical-free fix for absolutely anyone that's struggling with low pH.
I will say you have to rinse this THOROUGHLY. Rinse and drain and rinse and drain and do that about 30 times until your water is clear. Then rinse and drain a few more for good measure.
I don't know how long it will last, or if I will eventually have to remove it so it doesn't raise the ph too much, but it did its job without me having to add chemicals to the tank. My kid picked out the pretty shells, so both kid and fish are happy. Seems like a quality product!
I would prefer not to use the chemical alternatives because they can kill your fish by raising the pH too quickly, plus they do not stabilize it, so it's a continuous battle. No thank you.
