Holy Chlorine, Batman!!

[tonyl]

FYI....I just changed my 9 year old liner DIY...18X36 sport pool, 20k gallons, filling back up right now.

When the pool was installed in late fall, they added EIGHT gallons of 12% pool bleach. No pump to circulate, they left everything winterized. Told me to add EIGHT gallons again in the spring. After the spring, I learned not to do that again but also didn't notice any sudden fading. But over time....it certainly did, almost all the color was gone from the bottom despite being very conservative relative to shocking and chlorine levels.

But that's not all. After draining the pool I had my box cutter ready to section it for removal. Came in handy for the sides as they were still pliable, but the bottom? My index finger cut right through it turning it to glass like shards. More like thin plastic than vinyl. Popped and snapped any where I touched it. Had we not changed it this year somebody's foot would have gone right through it along the coves where it pulled back.

Just an FYI...sometimes the evidence of over chlorination shows up later...Tony
