    Do u only supplement cuttlebone if you have soft water?
    I have very hard water and have researching crabs. Would I need to add supplement or just if they need extra calcium?

    the cuttlebone is to provide your crabs with a source of calcium to strengthen their shell. I actually recommend giving your crabs eggs shell that you have been removed of the protein skin on it. That way it doesn't pollute your water and is a cheaper way of getting your crabs their calcium.

    I use cuttlebone. I boil it for a few minutes, let cool, and it sinks down in the tank. It takes a long time to disintegrate.

    I keep cuttlebone in all my invert tanks just so it's there if they want it. Not sure on crabs as I don't have any, but my snails and shrimp like grazing on it.
