I am just getting to the end of a SLAM and want to add DE to my sand filter to help the filtration. 1st attempt was yesterday and I added the 1/2cup recommended and seemed to be working and I had to go to work. Came home and filter had a low flow indication and high pressure on the filter. I back washed this morning and tried again with around 1/3 cup. About 2hrs later I had to back wash again because of high pressure and didn't add any more for now. My question, is this normal and filtering that much better than regular sand or am I using too much? My water is almost back to normal from SLAMing, just a little murky right now but not bad. Should I expect to have to backwash and put more DE in multiple times a day for a while?
How much DE is everyone else using on the Intex sand filters? Do you put it in dry or mix with water? I did it both ways and it seemed to work better wet. When I put it in dry it seemed like it passed through the sand filter.
Thanks in advance.
