What is the cheapest way to add calcium to a tank? I'm currently just adding the two-part solution, and it is ridiculous. I haven't jumped over to a calcium reactor yet, but do I need to be heading that way with SPS corals? I know people used to add those Dow Flakes, but it seems that was in the past. I appreciate any advice I can get on this! (Less important, but still a question is iodine. Is there an inexpensive route for adding that for my softies?)
Thanks,
Brad
