Shocking with Cal Hypo

[yossarian]

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.

Shocking with cal-hypo is just fine as long as it won't make your CH level too high. Given your current levels, there doesn't seem to be any chance of a problem.

I've done the same thing. It's a lot easier to carry, and if you need CH anyway, why not? You can use the bottom of Pool Calculator to estimate the effects of your CalHypo additions.

Exactly. It also has a much smaller footprint in my garage. I did check the Pool Calculator. I am not sure the cal hypo will get me to where I need to be, but I guess I can now use the supplemental calcium booster that the prior owner left behind.

Exactly!
