    Just filled Swim Spa and first Water test results ???

    Finally got my "new to me" swim spa filled after taking care of a few mechanical issues with the seals. This thing has been sitting empty for about a year since it was taken out of service by the previous owner
    I am new to this pool thing and want to use the BBB system... have added some bleach already as it filled.
    I picked up a Taylor test kit and here are my first water tests:

    FC - 4
    CC - .5
    ph - 8
    TA - 175
    CH - 170
    CYA - no reading ... dot stayed visible.

    So going to the Pool Calculator, I can figure out what I need to add but it seems I should maybe "Shock" it first and try to get rid of the CC ?
    Seems like adding all that stuff at once might be to much ...

    Suggestions?
    Thanks!

    CC <0.5 is nothing to be worried about. Did you fill it from a municipal water source? If you did it is likely that it is treated with monochloramines which will show up as CC.

    I don't see a need to shock it unless it had water trapped in its piping (not fully dry), and even then you can do a Overnight Chlorine Loss Test (OCLT) to see if something organic is consuming your FC. See: http://www.troublefreepool.com/pool-...rnight_fc_test

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    Yes... I filled from Municipal water which I know is really hard ... have had a softener for years.
    Will put in Bleach to get up to 7 and add Muratic acid to get the ph down and go from there.

    Will also do the overnight FC test...

    Thanks!
