Arizona in ground pool, sand filter, push pull backwash vale. 25,000 gallon + attached in ground spa.

Summary: Pool became a green monster after my palm trees were trimmed. Tons of shock and green algecide later (Swimtrine Plus - full container) pool turned a beautiful blue with all the dead algae on the bottom...sort of a cream color. I've been running the pool 24/7 every weekend in addition to my 8 hours at night, lots of back washing, vacuuming, and trying to keep my chemicals up (chlorine is good, pH is a bit low, just under 7.2). No matter what I do I cannot get rid of the following:

- Pool is insanely cloudy, cannot see bottom. I have put in tons of clarifier, including BioDex - Clearex 500, no beneficial results.
- When pool is circulating there is a TON of foam buildup on the surface. I thought it would pass after weeks of cleaning/back washing/maintenance, but so far it hasn't seemed to dissipate.

I have been checking the pool for sand to see if I may have a broken lateral, but have not come across any as of yet. Pool sand was changed out a year and a half ago, so I don't think I have something wrong with my filter, but I do notice when the pool first kicks on, the return jets blowing water from the system back into the pool are pushing in very cloudy water. It's almost as if the filter is not catching it. It seems like no matter what I do, I cannot fix these issues!
