I was all shrivled up... I added the new rock and sand because I did not have enough in there originaly, and I had a friend give me 40 lbs of sand and 25 lbs of rock in exchange for a bag of salt. I now have a much more reef like tank. But it came at a cost... I think I completely lots mt frogspawn to brown jelly and it spread to the yellow side of my sun coral, and my green brain is still not happy but I see on brown on it.
