All my chemicals have been right on. I noticed a white film yesterday laying on top of the pool figure I would skim it today and nope its not coming off with skimming so what could this be and how do I get rid of it? Now the kids did use the pool last weekend and I thought maybe sun tan lotion but I would think I would show before yesterday. Any advice.
Here are my chemicals this morning using the TF-100 and I also use the BBB method
FC 4 (I usually keep around 5 so ill prob add today but as 5 yesterday)
CH 100 (I have vinyl)
