Salt Water pool
1st Round of Muriatic Acid (3 Litres), No aeration yet
2nd Round of Muriatic Acid (3 Litres), Added Aeration, plus added CYA in sock for slow dilution
1st round dropped TA by 50 PPM, 2nd round did not drop it by any.
Pool has circulated for 8 hours between tests.
I never seen this happen before, is there a logical answer, could it have something to do with adding CYA?
I started the 3rd round (3 Litres) tomorrow I will test again
