I've read that cuttlebone is a good source of calcium for my snail. Will this affect water params? Also will it affect my other fish? I have a betta, 4 panda cories, 3 cory juliis, and of course, my mystery snail. If it's safe, how should I go about adding it? Just toss it in.. or little pieces.. etc.. thanks for any and all advice!

I just tossed in the cuttlebone I have in my tank with my Betta and mystery snails. Has never seem to have affected my betta.

Your idea is fine, you may want to boil a chunck and then throw it in. I use egg shells crushed into power. I summer, I put the egg shell in a small container and put it outside and wait for algea to grow all over it. That is great for Shrimp and snails.

I use cuttlebones as well, never had problems with my fish. Some will nibble on them, but I don't think it'll hurt them. In fact, in my nursery where I have some snails and cuttle bone, the kids will nibble on them and it's a good source of calcium they need for their bones(especially their spines) which can be harder to get into baby fishies.

The only issue I had with them, was sometimes they can make the water murky for a short time. It usually clears up, but I didn't boil them or wash them first, so like another said, I'd suggest you either let them soak in hot water(I wouldn't suggest boiling...that may make them fall to pieces and you will want a chunk your snails can walk across to absorb it), or rinse them well in warm water. It may lessen that chance, though it was never bad, just kinda annoying and usually clears up after a day or two.
