My current values are:
My water is not very clear. I can see the bottom and it appears swimmable, but it just doesn't look quite right. I wanted to shock and read that I needed to take my FC up to 15 and keep it there. How long do I keep it there?
In the mean time, I added a half cup of DE to my sand filter. This caused the pressure to go up by 1 to 2 lbs of pressure after 20 min. After 3 hours it is up to 35psi. The normal psi is 22-24psi. I have backwashed and added the DE three times. Each time it goes up 1 to 2 lbs in the first 20 minutes but ends up rising 10-15 psi within 3 hours. Do I have too much DE or is it simply doing its job?
My pool is near a lot of blowing dirt from crops nearby. The dirt settles to the bottom and is then filtered by an infloor system pushing debris to the sand filter.
