Kalita Posted May 9, 2021 Share Posted May 9, 2021 So I've read about folks using cuttlebones in their tanks, especially shrimp and snail tanks, as a calcium supply instead of crushed coral. What your thoughts and experiences? Link to comment Share on other sites More sharing options...
Administrators Cory Posted May 9, 2021 Administrators Share Posted May 9, 2021 For me personally in my testing cuttlebone has never made a difference. I suppose it's better than nothing but leaves a lot to be desired when trying to get calcium to my shrimp and snails. I prefer wonder shells, equilibrium, zoo med banquet blocks, tums etc. Link to comment Share on other sites More sharing options...
Kalita Posted May 9, 2021 Author Share Posted May 9, 2021 (edited) @Cory Ok, thanks. I'll likely leave it in (it's in the filter compartment right now and I have no other use for it) and try some of the other things you suggested. I only have 3 RCS in there now but as they breed, I'd like to make sure there's adequate calcium to support and maintain the population growth.
