Okay, the subject line says it all, the splash put spots on my pants and maybe affected a flagstone. I ordered a Liquidator. I can buy a paver to put the Liquidator on beside my equipment pad. My point is, adding liquid chlorine directly to the pool is not without its own set of hazards. I knew this would happen. it did take 40 days. I will not make the same mistake again. All in all, I am a believer in TFP, but adding that liquid chlorine at night is a prob. to me.
