    No CH reading

    Today my CH test did not turn red. Is that a bad thing?
    13,000 gal IG plaster, SWG, heyward cartridge, variable speed pump. attached spa w/ dual spill-overs & sun shelf. In direct sunlight all day. Pool is "partially above ground" with one-side of the pool serving as the retaining wall, as our back yard is on a large slope. Original build date: 4/11/2014. Entire pool was completely stripped and refinished less than a year after construction because of leaks. Re-opened: 5/7/2015

    Yes it is. What has your CH been in the past? When did you test last?

    Any chance you might have forgotten one of the reagents, or grabbed the wrong bottle?

    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!

    Try testing tap water to see if your test works.

    What happens when you add r-0011?

    Did you use 20 drops of r-0010?

    Do you have copper in the water?
