Our pool opened to a green swamp, which was bad enough, but the CYA levels were very low, as were the calcium levels. I have gotten to brining the CYA up, but have not yet adjusted the calcium yet (I am more concerned with shocking the algae). Is there any reason why I shouldn't consider shocking with cal-hypo instead of bleach so that I can take advantage of the fringe benefit of raising the calcium hardness?
Our calcium is around 110 right now and we have a gunnite pool. Last fall, we closed the pool with a calcium hardness of around 320.
