I have a 15000 gal salt water pool I'm having trouble with. I have a compupool 16 chlorinator.
I just took apart the DE filter and cleaned it out. It had green slime all over it. Pool is a little green.
After I cleaned it and added 6 lbs of DE it ran fine for a week. Then every time I back flush it, it goes from 14PSI to 25 PSI in 24 hours. The filter is running 24H so I can clean out the murkiness and get the chlorine up but it's not working even though the Chlorinaotr is at 100%. I've cleaned that out as well
My back flush procedure is, backflush for 30 Seconds, filter 30 seconds, and I repeat that for 3-4 times. then add 3 lbs of DE
What am I doing wrong?
