Forgive my noob questions. I have read ad nauseum through pool school and searched quite a few start up threads etc.
Some background. Pool start up was Monday this week. Pool was shocked by the tech. He went through the chems and testing etc. I am in the 2 week brushing plaster process. Brushing early morning and in the evenings.
1) When is the best time to test the water, before or after brushing the plaster?
2) Is it normal that I have already had to add 1/2 gallon of Muriatic Acid? The ph last night was purple on the test kit they left for me. Will test again this evening.
3) In regards to chlorine tablets, is it best to add one tablet at a time to the skimmer basket or should I add more? I bought 2 at Home Depot and put one tablet in this morning as the CH did not change color on test kit.
I plan on having the water tested at a pool store this evening.
