Here are my initial test results. What do I act on first?
My gut says to adress the CYA as the manufacturer's suggested range is 60-80 ppm. While the CH is at the high end of the ideal range proposed by AquaLogic/ Goldline (200-400 ppm), I have some landscaping dirt blowing into the pool that may be causing the elevated number. The calculator indicates nearly five pounds of cyanuric acid. Can I pour this into the skimmer basket even though I use a cartridge filter? What other parameters are likely to change as a result of increasing the CYA? Where do I go first? Also, as I am transitioning from having a pool service (he shows up on Fridays, dumps in some muriatic acid and leaves, uh exits) should I wait until after he does his thing on Friday since it takes a week for the CYA to dissolve?
