Hi Skamp,

Congrats on the pool. Hope your weather is nice enough that you won't have to wait too long to jump right on in.

My own fill water was in the 70-90 range for calcium too. Some nice folks right on this site recommended using calcium hypochlorite to chlorinate my pool in the early days, taking care of chlorine and calcium at the same time. Worked out great so that by the time the SWCG was ready to come online, I had around 200 CH, right where I wanted it to be.
