Hi all, just a couple of quick questions for those of you who add D.E. to your sand filters:
1. I know you have to add D.E. after you backwash because it flushes it all out. Do you add more D.E. every time you backwash? Or do you just add some after a heavy swimming load/rain storm, etc.?
2. Does the PSI increase of 1 also change when you backwash? You're supposed to backwash when the normal pressure goes up 25%. So if you sit at 15, you would backwash at ~18.75. With the PSI going up 1 with D.E. to 16, do I now backwash at 20, or do I stick with the original 18.75?
Thank you all in advance! After 3 years of pool ownership, I finally decided to listen to you guys and am in the process of SLAMing my pool right now. My water has never looked clearer or more beautiful than it does right now mid SLAM. I'm so excited to be able to maintain this thing looking so good all Summer.
