SKBok, it was going to be FOWLR but I couldn't resist so I've decided to go full blown reef. I had to dig deep into my pocket and some savings but it's what I really want. As of now, my calcium is a steady 300 and I have 3 frags: green striped mushroom, xenia, and yellow velvet finger acropora. I dosed a liter of RO water mixed with 1/2 teaspoon of kalk (as recommended on the kalk bottle) over about a 12 hour span and the calcium did not budge. Still 300.
