I have new pool. Opened mid March this year.
My FC readings have always been low - around .5 to 1.0. Also, my CYA is low or almost non existent. PH is usually high - around 8.2
The water looks and feels great. I have SWG and Delta UV filter as well. I am wondering if the UV filter is doing its job - allowing me to keep the FC low.
I have not back washed the filter yet. Pressure is near start-up pressure.
Any advice would be appreciated.
