Good point Vinny on the PH raising toxicity of ammonia. I believe even John from reefcleaners.org mentions that in his email after ordering when acclimating snails and crabs to just float them and throw them in because of that very reason....I remember when I put my first coral in I sat there dripping it and all for a zoa frag. lol. How much you learn in this hobby. I'm sure those coral farmers laugh at us when it comes to a lot more things than just air exposure.
