    Cleaning the view tube

    My CYA view tube is getting cloudy looking. I rinse it well after testing, but apparently not well enough. Since a grey dot will read differently than a black dot, how to clean it? Acid? Bleach? Ammonia? Anybody got a clue?

    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!

    No answer, but I thought the same thing last time I tested mine. Actually my thought was that the surface of the tube is etched rather than in need of cleaning, but i'm interested in the responses to this...

    6% bleach should clean it. Fill it up, let it sit a bit, then rinse well.
