Neighbor has a custom hot tub and has had problems keeping the water nice.
I finaly helped him to get it cleared up with some good shocking and Ph control.
He called me a couple days ago and said the Ph was down a little bit, and I said that was normal when you use trichlor tabs in a floater, and told him to get a box of borax and that would bring it up, and then keep a close eye on it everyday. Today I went over and used the taylor 2005 test kit and got something weird. The fc test looked good for a few seconds and then the purple just vanished to clear. So I did the cc test and the water in the tube turned a brown rusty color.
what the keck is going on. Ph was right on 7.5 but I couldn't even get the alkalinity test to show up right. HELP!!
