...so, my SPS tank was doing fine. I added a 24x24x12 frag tank to my 350G system and used a 30lb bag of black sand since I had it. Over the next three months, my SPS just started to get brown and even some of the more touchy ones (dragons and echinata) started to STN near the edges of the encrusting. After a week of thinking, I replaced the black sand with some regular. About a week later, and a water change, the SPS are back on the road to looking good again.
Anybody else hear/experience this? I am totally open to the fact that it was just me. This sand stuck to all of my magnets, so could it be elevated iron?
The montis, zoas and LPS that I had were all fine. I have looked online for black sand tanks, and most are mixed reefs with few, if any, SPS.
