stn/rtn

Hello all, Apologies in advance for the long post... I'm having some issues with my SPS that have just begun in the last week or so. Details on my tank below. I have made no major changes since I've added these frags to the tank 2 months ago. Some of them looked to be coloring up a bit and...

I’m having some really weird stn issues going in in my tank. It’s a 10 gallon and has been going good for a couple weeks i’ve been having some really bad tissue loss on some sps and some lps that i have no idea what it is or what to do to treat. 1.025 sg P04 0.00 (hanna phosphate ULR) NO3 8.0...
