PB did what I think was an Acid Startup after letting pool sit for 4 days after fill water.
I don't want to repeat all the awful details of the 2 hr startup as they on my build thread but here are a few:
After the startup my PH went from 7.5 to something way below 6.8 as PH test was below lowest mark and bright yellow. PB put in 2 gallons of 31% Muriatic Acid, 2 gallons of Chlorine and a 1 gallon pail of granules he said was Stabilizer but I had zero CYA. Per Pool Math PH could have got down to 3.5
PB told me to brush daily and left for a 2 week vacation. I asked if I should bring the PH up to 7.5 after a few days. He said it will rise to that after about a week.
After a week I still was reading below 6.8 PH and TA zero. CH 150.
So decided researched old threads and got some A&H Washing Soda. Per Pool Math (Effects of Adding Chemicals) last evening I added 2 boxes (110 oz.) which should have brought PH up to about 7.5 if it was just under 6.
Water turned cloudy last night but this morning it is clear.
PH 8.2
TA 40
FC 5
CYA 20
CH 150
My question is do I add acid to bring PH down to 7.5?
New Plaster will be increasing PH but I'm temporarily using Trichlor tablets and they are Acidic.
