I'm been following this forums for about a week now and I like what I'm reading.
This is my 1st year owning a pool (purchased with house). I had a "pro" open the pool. We recently added SWG to the system.
After reading some info and testing, I see my CYA is off the charts. I don't have a true CYA test kit (order is in the mail), so I've been subjected to using test strips. CYA registers somewhere between 100-300. I did a 50/50 test and the result was 30-50ppm. I would like it to be at 60-80ppm due to SWG.
I partially drained the pool twice. I have an inground vinyl. 21000 gallons. I drained from midskimmer level to below skimmer and then refilled with tap. Is it safe to drain lower? I've heard horror stories. I have been draining using main drain in deep end. Closed valves on other skimmers. Is this safe? How many more time will have have to do this partial drain procedure until I see progress?
The entire procedure is very frustrating because I feel like I'm not seeing results with amount of time it has taken to do the two partial drains and refills.
Any advice would be greatly appreciated.
32' x 16', 8' deep at the deep end, about 3' shallow end.
