So, I got a little over zealous and bought a bunch of coral from a website to take advantage of their sale. I bought 20 coral to be exact, mostly zoas, LPS, and softies. My tank is 10 months old, 90G, very stable now, and the 10 pieces of coral I have in there now are striving. 1. Will I crash the tank by adding so many coral at one time? 2. What should I watch out for after adding them? Any maintenance things I should do?
