Have you checked your Alk during all this time, if not you need to bring up to 100 ppm slowly as CarlD mentions above. I think that is why your pH keeps dropping.

Yes, it has been at 50 from the start. whatever is causing the pH to drop I'm sure is having an easier time doing so because of the low Alk but I don't think the Alk itself is responsible for the drop. I am testing after each 2lbs of BS.Originally Posted by PatL34
Re: PH/Alk Plan of attack
Changes in pool chemistry can take time Wayne, so be patient. The low Alk is definitely responsible for the continuing drop, and as you increase it you will be able to control the pH more easily. Testing the way you are doing is excellent.
Keep us posted as to what is happening.

Re: PH/Alk Plan of attack
Where getting there. I set myself back a bit, I had to top the pool off at lunch yesterday and forgot to turn it off when I left. Needless to say, I over filled it "slightly".
Anyway. pH is now 7.4 and alk is 70, it probably would have been higher if not for my fantastic memory.Interestingly, with the Cya as low as it is, 10-20, it's holding Cl fairly well. Full sun and hot yesterday and the Cl was still 3ppm in the evening from 6ppm in the morning.
The white haze is clearing, slowly. It has been 3 days running the pump 27/7. Should it take this long to clear?
Re: PH/Alk Plan of attack
Hang in there, and keep the pump on. Ben's (Pooldoc's) position has always been that AG pool filters are notoriously undersized, so it tends to take longer to filter dead algae out of an AG pool than from an IG.

OK,
pH seems to have settled in at 7.6 and I have the Alk to 110. As to the pump/filter being matched; I have a Hayward GM152 sand filter with a Haward UN series 1hp pump. Not sure if this is a good match or the filter good enough for a 12,000 gallon pool. It was all given to me last year.
Still hazy but getting better...
