Re: Numbers perfect, SLAMing for Days, still not clear
After 10+ years on the forum, it is pretty clear that Intex equipment is under powered and generally does a poor job trying to clear a pool. We see it time and time again. You didn't answer, but I am assuming that is an intex pump and filter.
That said, you can get that pool clear, it is just going to take some time.
1. If your pressure is staying at 12 psi, why are you backwashing? You should only backwash after a 25% rise in psi.....not before that.
2. When you backwash, are you seeing debris and dirty water in the discharge?
3. With a CYA of 30 ppm, your FC should be around 12 maybe 14........why are you at 22?
4. What did the water look like when you started the SLAM? Exactly how many days have you been SLAMming and how consistent have you been keeping the FC around 12 ppm?
5. It is pointless to vacuum to waste (when your water looks like yours) unless you have solid debris on the bottom. Keep filtering and running your pump 24/7.
The SLAM process is actually a fairly precise method of getting your pool clean but you have to be true to the SLAM article. Do EVERYTHING the article says to do but there is seldom any reason to do any more.
