Still fairly new to all of this. In the past month I have drained my pool completey, acid washed it, filled it back up. Since i have done this my pool is nice and blue, well blue anyway. I notice white powder in the bottom of my pool all the time now. I have swept and vacuumed the pool every other day for the past week and still cloudy and powdery. I noticed tonight that when my pump kicked on my returns were feeding the white powder into my pool. I have a D.E Filter and I backwashed 5 days after filling my pool back up. I was told to wait that long since i added stabilizer when i filled the pool. My test results are:
It must be stable because I am not having to add anything for the past 3 days. I test every night and every morning since i filled the pool 2 weeks ago. I use bleech to add the Chlorine and I have one float with 3ea 3" tabs in it. My pool is 18,000 gallon in ground gunite pool with white walls and an attached jacuzzi. I have the main drain open all the time unless i am vacuuming, I have the skimmers open all the time, I have the jacuzzi drain partially open unless we are in it then i close the drain. I run my polaris 360 when the pump is on 10 hours a day. I do not have a multi position valve. I backwash using a T style valve.
What do i need to do to get the returns to stop feeding the powder (I am assuming D.E.) back into the pool?
