    new pool readings

    I just moved into a house with a swg pool (see sig for details). The pool is algae free and nice and clear. After adding water to get it to the right level, I got out my Taylor K-2006 test kit and took the following readings late last night:

    FC = 6
    CC = 0.5 (one drop)
    pH = 8.0 (or higher)
    TA = 80-90
    CH = 190
    CYA = 32 (higher than 30, lower than 35)
    Salt = 2750 (aqua check test strip) or 2900 (SWG control panel)
    Borate = 15 (insta-test test strip)

    I am trying to figure out the order to adjust all of this. I do plan on increasing the borates to 50 at some point, but not until my other numbers look better. I used the pool calculator to get the amounts. I am going to lower the percent on the SWG by 5% (although, with a little CC present maybe not).
    Screened in 15,000 gallon in-ground plaster SWG pool with attached spa. Borates 40-50ppm. 1.5 HP pump. Propane heater. Taylor K-2006 test kit.

    Re: new pool readings

    Start by lowering the PH to around 7.2. That will also lower your TA a little (which is high but not time critical).

    The start working on raising CYA and CH. CYA should be between 70 and 80 for a SWG pool. CH should be between 250 and 350 for a plaster pool.

    The raising the salt level just a little (say to 3200) and Borate to 40 or 50 are both lower priorities, but worth getting around to eventually.
