The water fill on our new pool was complete on 8/2/09. The fresh water looked like this:
I added 64oz of CYA (all I had at the time), and 24 oz of muriatic acid to try to drop the PH to 7.5. Also added salt to get the level up to 3300 PPM.
I added ½ of the recommended CH in small doses throughout the day.
On 8/4/09 (I also took a water sample to the PD and his numbers matched mine exactly):
I added another 64oz of CYA (got about 1.5 lbs to go), the last half of the CH and 56oz of muriatic acid to drop the TA to 70 (based upon a PH drop to 7.0). I built a “sprinkler” on one of the return jets to spray the return water into the air…to raise the PH.
This evening, 08/05/09, I think the numbers look pretty good with the exception of the TA. It is still at 100. It only dropped 10 points after the addition of 56oz of MA.
I did not do a CYA test as I will be adding the last part of the CYA this evening. I NEED some guidance on what to do to get the TA to drop. I followed the recommendations on the Pool Computer for the amount of MA…but the TA drop is negligible. What do I do now? …Keep adding MA till something happens?
