Zoo Med Dr.Turtle Slow-Release Calcium Block (Pack of 5)

I have 6 snails (1 black racer nerite and 5 black mystery snails). They were developing white lines along their shells. It was recommended to use a slow-release calcium block for the tank to help put the mineral back into their shells to keep them healthy. It was definitely worked well! The lines have finally vanished and they seem to be growing larger now. They are easy to use, just open it and plop it in there... It is safe for other freshwater fish in the tank. (I have a 20 gal. tank with a Dragon Scale Betta Fish, 6 green cory catfish, and 5 Zebra-Striped Tetra)... I originally had 6 tetras.... but the tiniest one did not make it... I am not sure exactly what happened... It could have been that it was born differently and just did not make it or he pissed off Wonton(my betta fish) for the last time and he head-butted him into the glass and the catfish and snails (being the scavengers that they are) ate as much of his tiny body... Only discovered the carcass and no more tiny tetra (we named him Kratos since small fishies deserve badass names...

Does what it says it does.My turtle is happy and healthy.

After 2 tablets in tank the turtles shell is looking much healthier. I would buy again!

Can just toss in tank and works like a charm

Each prepackaged in its own packaging, making it easier to save and use 1 at a time. Best deal anywhere, as they are as cheap as 3 dollars anywhere... but this deal makes them even cheaper than that. Definitely would recommend and will also buy again when needed, this seller.
