Pool still cloudy white. Been a week today... This stinks.

[Lawrosa]

Yeah. Sand is one yr old. New laterals from last yr. Took apart, sand is good and all there. Took hose and stuck it in to clean it good. New spidergasket. Pressure rises overnight 6 psi or so on high, low goes up 2-4 psi, but on low output is really reduced so I backwash. On high it seems to stop before 20 psi. Starts at 12psi.


Just tested pool.

FC 2
Added 5 drops of r3 looks inbetween 2 and 3. 2.5??? TC 2.5 ????
Is that .5 CC???
PH 7.2. Orange color. One color above 6.8
Alk 80. 8 drops to change from green to red.
Hardness like I said I have this kit. It changes pink to blue in one drop. 17.1 ppm or 1 gpg.

CYA is at 30

What else should I test for?
What defect should I be looking at with the sand filter? I see nothing wrong. The only thing is where the valve sits on the riser/lateral. Is there a O ring. It looks like the valve just sits on the pipe. Its tight. To get the valve off you need to rotate it to get it off. Otherwise the laterals want to come out.
