picking up some CH increaser. There was a guy there getting algaecide, shock, clarifier, etc. They bought a house with a pool that he has been trying to clean up for a month. He gave up on the pool store. I couldn't help myself and started talking about BBB. He agreed to try it after I offered to pay for the bleach (he paid for it). I told him about TFP and Pool School, maybe he'll sign up.
