Weco ProductsWonder Shell Natural Minerals (3 Pack), Small

I have several mystery snails and the biggest injured his foot. He spent some time in snail ICU (a bowl with a small amount of tank water floated at the top of the tank) and he was of course sluggish. I added a little of one of these that I crushed into powder, and he perked up right away. I added another to the tank for him and my others and their shells look great and they are very active. Good price and works for my guys. As far as the flavor rating, ??? I dunno, they won’t tell me

I put 3 in my aquarium hoping to add some calcium and raise the PH level for my snails but it stayed at 6.4 - too low. I’ve moved on to try argonite now. I found them expensive and only lasted a month

I was worried about how sluggish my nerite snails were in my rather acid water so I broke the wondershell into small pieces and add a piece regularly in the same place in the water. The nerite snails moved straight over that side and hung around near them and got a lot more lively straight away.

Great 👍

One small shell quickly increased the GH in my 5.5 gallon tank. My water has a GH near zero and after a few days it had almost maxed out the GH on the test strip. The shells do dissolve within a couple weeks, but that's what they're made for. Put in a section of the tank with less water flow to slow them down.
