cloudy from calcium?

[tebstan]

I'm doing weekly 10-15% because I think the rock was still curing when I got it. I don't feel it's cycled yet, though it's had its algae phases and water tests perfect. (aside from calcium...) It went through the brown algae phase, and then the cyano phase for a few weeks. Now I have very little hair algae, just one tiny tuft on a rock that's almost cute.
I added some purple tech a few times to get some coraline growing. I'll admit, I didn't measure exactly, but I followed the directions otherwise. And that was a few weeks ago. I got the calcium levels up and stopped adding. I didn't take into account that Oceanic salt was adding calcium as well. Why the ban on Oceanic? This is my blunder, not the salt's falt. Any other specifics?

No way I'm switching to RO. Mostly, because I'm five foot tall with a 90 gal and no one to help me. Someday, when the tank is more developed, I might look at getting one of my own, but for now it's not worth the trouble. My tap reads no phosphates, I use dechlorinator, and I don't believe there's much flouride added to be of danger to what I'm keeping right now. I kept discus and such in tap, and did fine. RO is just as finicky as tap - the quality is not the same every time, every place. The only sure benefit I've seen to RO tanks is reduced algae, and I don't have an algae problem.
