Review on Weco 37783000 Wonder Shell Ornament by Hope Tribolet

I originally bought this to help with calcium in my aquarium for my snails, shrimp and crabs. I will say as soon as it was put in there it started bubbling and releasing minerals. I know it has good stuff in it because I see MTS snails nibbling on it all the time, but the calcium in the pillar is more what I'm looking for. I will definitely buy this again. Water quality indicators have not changed. Leaks out pretty quickly, and if you do big water changes like me, you probably need to change more than recommended. Also loses its shell shape quickly so don't flaunt it unless you like seeing a big white lump after a week lol.
