    Re: Whats your fill water test results?

    If you have city water then you must be the guy furthest away from the treatment plant since you dont have any FC. Here is mine on city water.
    FC: 1
    pH: 7.4
    TA: 200
    CH: 200
    CYA: 0
    We are at the end of the water line, at least on this side of the treatment plant.

    We are on city water and we are pretty far down the line. I'll probably test it again soon just for giggles and grins.

    Whats your fill water test results?

    Best to take a water sample from a spigot outside the house and closest to the main line running into your home. That eliminates sources of contamination from the house piping. I'll grab a sample later today from the spigot that my auto fill line is hooked up to as that will be the most accurate sample of what goes into the pool.

    Eastside Tucson, Water District #7

    Let 10 gallons run from spigot that auto fill is attached to, then tested a water sample -

    FC 1
    CC 1
    TA 120
    CH 250
    pH 8.0+

    Obviously no CYA. Would have to check with Tucson water website to see what TDS, nitrates, phosphates and metals are but I know they always test below EPA regs for those.

    You guys that have low CH levels, do you have water softeners?

    Water samples should be taken from an external spigot near the water inlet to the home, not from a tap. That would avoid confounding results caused by softeners. External spigots are usually plumbed separate from the other water lines in the house to avoid watering landscape with softened water.

    Re: Whats your fill water test results?

    I do have a softener but like Sunny said, took my sample from outdoor spigot where I normally fill pool. Without the hose, ran for a minute before sampling.

    Why is that? For pool water, isn't it more problematic to have that high of a TA then it is that high of a CH? Or are you saying that because it is easier to reduce TA then to reduce CH?
