So, my tank has been up for about a month or so and I'm a little worried that I'm not getting any coralline growth. I've seen little tiny spots on the live rock here and there but nothing that really looks good. My parameters all check out but I don't have a phosphate test kit, so I'm a little uninformed on the subject(given the diatom blooms I bet there's a moderate amount, though). Any of the coralline that comes on the LR from the corals I get usually bleach after a few days. Is they're any advice that could be given to give my coralline a jump start?
