Wow that is a big boy that's for sure...I'm going to start building in mid January... WOO WOO...... Sounds like that Humu was an *** of a fish, I got mine and my foxface from the same tank at the store, and the first 2months we had them the humu was always out and cruising around and the foxface hid in his cave, that is while i was in the room and would wait till I was gone to eat his seaweed...NOT hes like OH YEAH YOU ARE THE FOOD GUY!!! SWEET.... and the Humu doesn't even mess with him.... So i have a question for Mr. Reef...... would it be beneficial to have a calcium reactor on my tank when i get it set up?? or will a kalkwasser drip in my sump work just as well.. As far as Chemicals go im not worried about the $$, i just REALLY like DIY stuff...
