Yesterday I went to check the water temperature in my pool and to my surprise, the white rope used to attached the thermometer snapped right off when I pulled lightly on it. I tried tying another knot, but the rope snaps off right away, with little to no force. I can actually break it in little pieces just by pulling with my 2 fingers. It's the "standard" pool thermometer type white rope (if there's anything like that).
This got me concerned with the chemistry of my water. Is possible that something in there would cause that? Could this also affect my vinyl liner? or is it just a bad rope...
The thermometer (and rope) are almost new and were in the water only for a month in the fall and 2 months this spring.
I have a Taylor K2006 and here are my numbers:
I have a goldline SWG running ar 9% and my PH has been very stable since I added the borax. I did 2 shocks with dichlor bags at the opening of the pool and got the FC pretty high at 15-20 and I didn't have any CYA at that time. I also poured a gallon of acid in the pool when going to Borax, but I did it slowly, following the instructions in the stickie.
