I read a recipe for homemade calcium blocks in a Red Eared Slider book somewhere along the line, but I can't seem to remember it.
Has anyone tried to make their own? Those little things get expensive. So far I've figured out that it's just calcium sulfate, but what else should go in it? I could put some turtle vitamin powder in there too, but would they get it if it's just released through the water?
I've heard of plaster of paris being used, because it's basically just calcium. I found a non-toxic kind, but I'm still not sure if I should use it, too scared to try without some collaboration with what other people have heard.
