Day 2...

Hi Ben. I got the items you suggested (borax, OTO/Phenol Red test kit, 8.5% bleach - I have 19 jugs on hand now (121oz each).

I used the OTO kit to check CL and pH to see how it matched up with the Taylor kit.

FC - 0
pH - 7.2 (before adding borax; I'll test again in about an hour)

So it matches the Taylor kit results.

This evening I'll add the bleach as you recommended.

Is it OK to let the pool go all day with 0 CL???
