    Pool turned green in less than 8 hours.

    Pool was clean this morning and now is green about 8 hours later. Looks the guy who you told had a metal problem. Ph 6.8, chlorine 20 and FC 1. Help please. Not sure what to do.

    Welcome to TFP.

    Post a full set of test results.

    If I read the numbers like you posted them you have 19 ppm cc's which says you really need to shock.

    Raise your pH to at least 7.2! What do you mean by "Chlorine 20?" Do you mean Total Chlorine (TC) = 20, and Free Chlorine (FC) = 1? If so that means you have 19 Combined Chlorine (CC) which is bad and you need to go through the shock process. What type of test are you using to get this result?

    Is the water a clear transparent green, of an opaque/cloudy/murky green?
