I need reassurance. Short history: Last spring our CYA was out of control. Drained, refilled, drained, refilled. TA was out of control. Acid and aeration until we wore out the compressor and had to buy another one. Everything was great the rest of the summer. Uncovered the pool two weeks ago, didn't look too bad. Hit it with Clorox and ordered a Test kit refill. It came yesterday. I tested the water this morning and I have 0 stabilizer!! Here is where I need forgiveness. I couldn't believe it so I took a sample to the PS. I know it's forbidden, but I was weak. They said I have 0 CYA also. Here are their numbers. FC 7.68, PH 7.7, Cal 270, ALK 120 and the ever present Phosphates 300. (I know to not get excited about that number.)
Here are my test kit numbers: FC 13.5, CC .5, ALK 140, Cal 300, Ph 7.8. I have no confidence when it comes to my ability to color compare the Ph or when the Alk and Cal actually "change" color, so those could be off.
OK - so where did my CYA go? Put the pool in 2003 and the stabilizer did nothing but go up. Then I got it where I want it by leaving a huge carbon footprint on the world, and now I want it back! I have read that it can turn to ammonia, but why did it choose this winter to do so and not when the CYA was over 200? Will you wonderful people will please tell me what to do now? Thanks.
