I've been reading your forum for a while now and I decided to finally ask for help.
I have a 17,500 gal in-ground pool, pebble tech
Sta-rite 3 filter
Pentair Variable speed pump
Pentair pool sweep with booster pump
Sun touch controller (don't get me started)
Roof panel solar
We have had the pool aprx 6 years. Beginning great, but then it seemed the next year and every year since then we have trouble with air in the system. This also seems to occur only after the solar gets turned on, but that could be a coincidence.
I have a pool service to do chemicals and skimmer baskets. I clean the filter cartridges. So far, I have cleaned them three times in the last month and a half this year. The second time I soaked them overnight with dish soap as per the site. Now again the system has too much air in it, the sweep won't run and the solar sounds like a marbles coming down the pipes. We replaced the filter cartridges last year.
The pool itself looks great, the chemicals are okay except the CYA is a little high, it is down at this time to 120 ppm from 220 ppm in the fall (thank god California got rain).
What am I doing wrong here????
Thanks so much for any comments or directing me to another posting.
