I'm not new to pools or BBB, but I have an out of town friend with a recently (vacation) green pool with a vinyl liner. She won't have a decent test kit until I get there on Thursday! I just need to know what to watch out for with a vinyl lining.
Her CYA is 150 (at least according to the strips) and I told her she needs to do some draining. But in case she doesn't want to do that, is it safe to dump in enough bleach to bring it up to 40ppm or so with her liner?
I also told her to bring down her Ph a bit from 7.6. She dumped in 5 174 oz bottles and according to her strip she held an off the chart (over 10) FC overnight?? I told her that wasn't enough at her CYA to attack the problem, but shouldn't the strip shown 0 in the morning?
Mostly vinyl question needs answered 'cause I don't want to damage her pool.
TIA to anyone helping soon. I leave in the morning!
Am I missing the search function here??
