I last posted a question in 07 and now have another one. I've been having some water balancing issues that I'm starting to get corrected except this one. I searched the forum for this problem before posting but didn't see anything like this.
I have a 20,000 gal Fiberglass pool. I'm using liquid chlorine as my only sanitizer. I placed 6lb of Stabilizer in my skimmer, checked over a week later and...I still show zero CYA. I'm using the Taylor K-2006 test kit and purchased the Stabilizer from Intheswim.com. It's 99% pure.
I have a brother who has become somewhat of a "poolman" and he too is stumped.
As much as I hated to I placed another 6lbs in the skimmer on Tuesday (6/26), checked it on Wednesday (I know it takes time to register but just wanted to see) and it was somewhat cloudy. I could see the dot with the tube completely filled. I then checked it last night again and guess what...it was completely clear!
It can only be 2 things right? Bad Stabilizer or bad reagent. I bought new reagent a year or so ago but didn't think it would go bad.
I'm still going to check in another week to see what the reading is but wanted to post to see if there could be something/anything that could be somehow destroying my CYA. I read that over the winter it's been known to be eaten by bacteria but not this...
my current readings as of last night were
water temp 84°
I added a half gallon of 12.5% chlorine. I plan on doing an OCLT tonight since I'm now not able to hold any chlorine (even over night).
thanks for any and all help.
