My question is what can you have in a reef tank that doesn't have such a high calcium demand so you don't have to keep replenishing beyond what your instant seawater gives (isn't it about 500-550ppm Calcium?) gives you?
Are there some kinds of reef tanks that don't need additional calcium beyond the reef water salt?

my calcium is around 440ish, if your looking to start your first tank softies are the way to go, frogspawn, hammers, xenia ect. they arnt as demanding and go up from there... ive noticed that SPS corals require constant dosing because they use so much but as a newbie anyways i just kill them...
