New liner, slippery feel

linda1 · Jul 14, 2022

We replaced our liner last month. I noticed that the sides and bottom have a slippery feel. I test my chlorine level every day and keep inline with my CYA level. I took a bright white cloth and wiped the sides of the pool and nothing showed up on the cloth. Do new liners have some sort of coating?

Does it get better with brushing ?

Yes, areas that I wiped now feel normal. I feel there was something on the new liner. Perhaps to keep it from sticking together in the box? I ran the dolphin 10 and bottom is feeling normal and I wiped some of the sides and those areas are now fine. Guess I'll never know for sure.

I seem to remember a couple of threads last season thinking their new liners were leeching oils for the first while.

Increase your brushing increments for now and see how it goes. Once it settles, slippery is usually algae needing brushing. It grows a biofilm over itself to protect it from harsh environments. It can then grow no matter your FC level and its why brushing is a big requirement of SLAMs. Each round takes off a protective layer and kills the next layer of growth. Then you have to brush again later. And again. And again.
