Someone posted yesterday on a Buy, Sell, Trade thread on Facebook yesterday about how bad their pool looks. Wanted help. Let's just say all of the replies go against most everything we believe on here. I will say this, more people use bleach than I realize. I've heard "locked up" among other terms. Of course most want them to take a sample to the local pool store. I did my part and told them to buy a good test kit and gave them the link to TFP. We will see how it goes. I just want people to know! I'm two years to the good!
