I have ordered replacement DPD powder.
OTO is not accurate[I know] but on opening I have added 10 litres of Hypochlorite 10.8% liquid - over 2 days.
Pool is fairly clear, and I do have enough DPD for maybe 2 more tests.
Our fill water is pretty good. 40 CH / 40 TA / PH 7.4
I had to remove about a foot of water and I did it from the top.
After mixing [circulating] Temp 52°F PH 7.4 / OTO CH 5 plus / TA 60 / CYA 30 / CH 75 / Borates I can't test but last year they were 50
What is the real deal on TA. Pool math says I need 1500g more baking Soda
