Hey Sanjay,, I just recently got into the reef hobby a year ago and was keeping few soft corals and LPS. Just 3 months ago I got into SPS and 2 weeks ago Acropora. I have been keeping saltwater fish for 10 years so have the patients needed to succeed with the reef aquarium.. Only I hate to learn from trial and error so i signed up for reef central just recently. From reading the threats Im assuing you take care of the aquarium in Penn state.? I am just outside of Pen state in clearfield Pa. and plan on coming to see the aquarium. I am planning on setting up a 150 gallon very soon. I have 760 watts on my 55 gallon and bought it knowing I want to upgrade tank size.. My major concern i have is calcium reactors,, I am reading reading reading about them but would love to have someone explain to me the do's and don't,, and around here there is no one who has a clue. I will post pictures of my corals fish and equipment very soon.
