    CYA/SWG question

    Just tested my water today and CYA was about 90-100 using the TF100 kit..From reading pool school, levels should be 80 for a SWP..Should I be worried about the elevated levels ? my FC is at 8ppm, ph 7.3, TA 80..Thanks!

    As long as you are sure that CYA is under 100, you can get by with your CYA level where it is. The thing to watch out for is that CYA levels above 100 will read as if they were 100, so you might actually have a higher CYA level. One way to double check this is to do the CYA test again, but this time mix equal parts of pool water and tap water together, do the CYA test on that, and multiply the result by two. As long as you get about 100 that way, you will be alright and can wait for the CYA level to come down on it's own.

    That doesn't make sense.... You should have seen some cloudiness. You didn't, by chance, forget to add the R-0013, did you? I made that mistake once.

    The sample should be 25% pool water, 25% tap water, and 50% R-0013.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
