Hi there: Continuing my education I decided to call my pool store and talk to them about their test results which said my cya was 100. I had to explain what cya was first to the youngster answering the phone. Then he had to get someone else. A young woman came on the phone and assured me in a non-nonsense, very brusk, tone that this was just perfect and basically what was my problem was the tone of her voice. This is where I spent my money getting my pool by the way..........#$%^&*Their water system testing is Wave Length.
So, I decided to call the pool store down the road about 8 miles. Wow what a difference, now their store is filled with lots of BAcquil BUT, also some chorline based product as well. They were very pleasant on the phone, asked me to bring in a water sample, knew exactly what cya was and yes, mine at 100 was, in their opinion too high. I talked about the BBB method to her, she knew exactly what I was talking about and allowed as how this was quite a viable method, although it did take some daily work etc....She was able to tell me what was wrong with the Simplicity system in terms of raising overall CYA, but their tests done with Pinpoint showed a CYA of 78, which she said was on the high side, but not horrendous. I commented that I had purchased the TAylor testing kit, she knew exactly what this was and pulled one off the shelf and proceeded to show me how to test for chlorine - mine is now too high after following my regular shop's shocking advice. She suggested I wait a few days, test my own chlorine and then come on back in to retest. She has been testing water for 16 years.......what a pleasant surprise,,,,,,,,and I didn't buy a thing. They do suggest some form of shock which does not raise the CYA as much and if it raises further to dump some water etc.
Might just be worth the drive, the Schnauzer likes drives!
