Dosing Kent Marine Liquid Calcium

Oops, I misread that. I was thinking Iodine:One drop per 10 gallons per week. I don't know what the dosing would be for calcium. I don't use it in my shrimp/snail tank. I do use the Kent Marine Iodine at the dosing above. I use cuttlebone for calcium. I cut it into chunks (it's like a hard sponge) and rubberband it to a rock to keep it submerged. You can just let it float like I did at first (it will eventually sink after months), but it's not very pretty. There is always a few snails sitting on it, and shrimp too.

I found this response from flaringshutter:

I dose at the recommended marine rate about every two or three days. Seems to be about right for my snails. Remember that the more snails you have, the more calcium you will need. At 2.5 gal/snail, I would use the bottle dosage. Less than that, say 2 gal/snail, you'll need a little more than recommended.

And that's still my method!

Be sure to mix it with tank water in a separate container, or add it when you're doing water changes, to minimize the risk of pure undiluted liquid calcium contacting your snails.
