We have a 10000 gallon pool. I will list my exact equipment when the sun comes up, but for the time being it is a chlorine pool with Pentair pump & cartridge filtration. The pool is caged.
We have a weekly pool service. The pool has always been crystal clear.
Last month we had a new Pebble Tec finish. It has been complete 3 weeks. The company that installed the finish filled the pool using city tap water and balanced it. They returned a few days later and got a reading of no chlorine in the pool. He added liquid chlorine.
My usual pool service took over a week after the pool was installed. His test showed no chlorine. The water is clear but not crystal like it was before the refinish.
He added a lot of liquid chlorine and left me some to put in every day which I did. When he returned the next week his test showed no chlorine in the pool.
So far there has been about 5 gallons of chlorine put into a new fill with no swimming going on. Pool man seems frustrated and cannot determine why the high demand. I asked him for the readings and this is what he gave me.
