We put our pool in last July and was having many problems for the first 3 weeks. I found this site and switched to bleach and everything has been great. Crystal clear every day all day. I did run my pump 24 hours a day.
About 3 weeks ago, I switched to 12 hours a day manual (8:00 a.m. to 8:00 p.m.). The pool stayed clear. About a week and half ago, I purchased a mechanical timer and had it installed. For the first week, everything was fine. Last week, we had tons of rain, so I only opened the pool on Wednesday to test the water and add chlorine. All readings were great. On Thursday, the same. I opened the pool on Friday and found cloudy water. All the readings were fine, except the chlorine as slightly low at 2.0 (pool math shows 3-7 for me). I ran the pump 24 hours a day until Sunday, brought the chlorine up to 8.0 on Thursday and kept it there until Sunday and everything was clear again (was a slow process). Mind you, my CC's were and always have registered 0.0 to 0.5.
So I ran the pump again 12 hours a day starting on Sunday (once the timer was installed I have been running it 2:00 a.m. to 7:00 a.m. and from 1:00 p.m. to 8:00 p.m.). Now it is Tuesday and water is cloudy again:
Here were my full test results from today:
PH 7.2 (my PH has been at 7.5 everyday since I can remember with a slight change when I added the boric acid about a month ago)
1. What is causing my PH to lower? I have a waterfall that we use a few days a week and have my returns pointing upwards.
2. Does the cloudy water have anything to do with the split schedule I am running on my pump? If not, could some rainwater be getting in there, or enough to make a difference?
3. Should I run the pump for 12 hours on, 12 hours off regardless of its impact?
To be clear, you can still see the bottom, it just isn't crystal clear like it normally is. And I have noticed that I am going throuhg more chroline daily than normal, was using about a bottle a day of 96 oz. 6%. The norm lately has been 2 bottles a day. Also, the water has been in the high 80's, but cooler temps have brought it down to about 78 in a pretty short period.
Thanks in advance for any help you all can give me!!
