Ok
I tested this morning. It has been 36 hours since I put anything in.
fc 5.0
c 0
ph 7.8

I think I will start with 1/2 a jug of bleach tonight. Will test first to see how far it dropped in 48 hours. Will report findings before and after the 1/2 of jug.
If not high enough then will add the whole jug
