My fellow pool owners, I need your help. I recently purchased a new home with an huge inground pool. I'm guessing it's 25k-30k gallons. It has a deep end and the shallow end wraps around to steps and a wading area. The filter is a Triton II sand. I have two motors, one dedicated to the filter and the other to the waterfall (They are relatively old so I'm unable to provide you with hps or manufacturerer information, but they seem to run great).
Approximately 2.5 weeks ago Arizona got hit with a dust storm that made our history books. My family awoke the next day to a thick layer of mud on the pebble tec of our pool. Not being familiar with how to manage such a situation involving a much larger pool than our previous one, I dumped 4 gallons of liquid chlorine and ran the filter non-stop for a week. AFter noticing that the water wasn't getting clear, I purchased a vacuum end to allow me to manually control vacuuming. While I was sucking up the dirt, I would see dirty water emitting from the return valves. After consulting with a couple pool experts, we realized that the sand likely "calcified" both after the storm and while the pool sat idle for 8 months while in foreclosure proceedings. I decided to change the sand last weekend, which was actually a realtively simple process. I now see very little dirt emitting from the return valves so I crossed it out as a culprit candidate.
So here we are today. See pics. I've dumped 2 more gallons of liquid chlorine into the pool, and added muriatic acid to ensure ph balance. It's been 3 days of running my pump for 10+ hours daily and I'm not noticing any progress. My daughter's back to school party is Aug 6th so I need your help.
Thank you so much for helping to guide this misguided soul.
