What I'm trying to do is raise my calcium level to choke out red algae that makes my tank look like crap by promoting good algae to grow. I only have 3 fish, 6 crabs and live rock and no other inverts. Because I mainly have a fish only tank right now, I only run my protein skimmer once a week. My question is since I 'm adding kalkwasser and a calcium supplement If I run my protein skimmer Will it take out all the stuff i'm adding and defeat my purpose?
