I think the problem may be the filter. I noticed green water coming out of it today. The algae must be clogging it. It is a D.E. filter.

I went to a pool store and got these readings
free and total chlorine were above 10 because I really shocked it
combined chlorine was less than .2 ppm
TA 150 but they said since I just added it would take a week to level off
ph 7.5
CH 335
CYA 12 they said to add 2 lbs but I can't because I have to keep changing the de in the filter
