Calcium Hydroxide is a proven standard for maintaining calcium concentration and alkalinity in closed marine aquaria. The calcium provided is directly used by calcifying organisms, and the hydroxide ions provided readily convert dissolved CO2 into bicarbonate and carbonate ions, which are also directly used by calcifying organisms. Our product is extremely pure and meets American Water Works Association and Water Chemical Codex requirements.
"Pound for pound and hands down the best acropora that I've came across in the entire country - the corals are incredibly healthy and fully colored, and most importantly of all grown with the love and care of a true hobbyist. Would 110% go with 5th Alarm 7 out of 7 days of any week in any given year"

Visited 5AC today and the corals and frags are amazing. Look exactly like the pictures. These are how they look in after a dip and 5 minutes in my tank.
