Well I went over there and he has 4.5ppm of FC. I told him to get some Cal-Hypo at the store. He told me he closed the pool green, which I din't know. He said he was yo-yo-ing all last summer, green, cloudy, clear.
His Alkalinity is 80 and his pH dropped a bit again. I told him to get some more Borax, which I swear by. If he dumps enough in to hit the magic ppm number, he'll be in better shape anyway.
