Review on Kent Marine Concentrated Calcium 8 Ounce by Crystal Garcia

I had very soft aquarium water and the shells of my mysterious snails became thin and brittle. I bought this in desperation so they were fine and it didn't take long for their shells to become hard and shiny. You look healthy and beautiful again. It calms me down. I would suggest this if you are a crazy snail lover like me or your snail shells don't look as good as mine. This will help a lot
