    testing while shocking

    I've read that testing pH is not possible while shocking. Are there any other tests that are influenced or made invalid by shocking that we should know about? Can we trust every other test while shocking besides pH?

    pH will llikely be off a little. TA will go blue-to-yellow instead of green-to-red. Seems like CH is also very pale and hard to read when I've done it with high FC.
    I think the chlorine bleaches out the dyes used in the indicators.

    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!
