Ok I can see Im going to be on this forum alot BTW thank you all for the info, I added some CYA to the pool today thru the skimmer but some of the crystals got out into the pool. Now I can see it laying in the crease at the bottom of the pool. Is this going to damage the vinyl liner? Should i vaccum it up or is it okay to let it dissolve where it is ??
Thanks

Kevin
