    No guys, he wants a "standard" to test his testing skills with.

    Engrav,

    Short answer : no

    Longer answer - make your own using hardness increaser (calcium chloride) and distilled water. Shouldn't be too hard, you just have to buy a bottle if CH increaser. Try the spa products section as its used/sold more often there and would come in smaller quantities.

    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!
