Yeah. I'm going to post it here. I ran out of time yesterday, and am supposed to be gone most of the day today.

But, keep filling and
#1 - Keep your pH low-ish => 7.0 - 7.2 . Add small doses of acid to maintain this. I told your husband how to use muriatic (plastic gloves, glasses, avoid splatters by partially submerging the jug before pouring, watch the fumes, 1 quart doses).
#2 - Do NOT add any calcium, alkalinity, baking soda, washing soda, hardness . . . NO MATTER WHAT ANYONE TELLS YOU.
#3 - If your pH gets too low, add a little borax. (1 box doses, added SLOWLY via the skimmer with the pump on)

Run your pump 24/7.

Lemme know when your pool is full and your pump is on.
