    In The middle of a shock and ran out of R-0871

    I placed an order with TFTestkits and it should be here tomorrow afternoon, but I'm in the thick of it and only have enough to test about 20ppm and my shock is at 28 (SWG pool with 70 CYA). Does anyone know where I can go pick some up ... I'm in the eastern panhandle of WV and my local Fhlor pool store doesn't carry any FAS/DPD testing supplies. Anyone in the area willing to help me out? Lesson learned ... order kit resupplies when I open the pool.

    Don't worry about it too much, just keep adding the approx. same amount of bleach and you'll be fine.

    It was a hard fought battle yesterday and today:

    Day 1 T1: 7PM - tested at 0.5-1.0ppm, added 5 gallons of 8.25% Bleach to reach 28ppm
    Day 1 T2: 8:45PM - tested at 2.5ppm! W.T.F! added another 5 gallons of 8.25% Bleach to reach 28ppm
    Day 1 T3: 10:45PM - tested at 13.0ppm ... heading in the right direction. Added another 3 gallons of 8.25% Bleach to reach 28ppm
    Day 2 T4: 8AM - tested 8.5ppm ... no bad considering the time involved. Added 5 gallons of 6% Bleach (I cleaned the store out of 8.25% the previous night) to reach 28ppm
    Day 2 T5: 10:45AM - tested 26.5ppm ... starting to take hold! Added 50oz. of 6% Bleach to reach 28ppm, turned on Chlorinator at 100%
    Day 2 T6: 12:15PM - tested 35.0ppm ... oops, overshot it! Turned off Chlorinator.
    Day 2 T7: 2:15PM - tested 31.0ppm ... turned Chlorinator on at 45% thinking that 100% adds 7ppm and off at 0% loses 4ppm.

    So 45% should allow it to drift down losing about 1ppm over each 2 hour period from now till sundown. I then plan on running it at 15% over night just to ensure it doesn't flatline and start losing the battle. Thoughts? Suggestions?

    Reduce to a 5ml (from 10 ml) sample and count each drop as 1 vs. 0.5 ppm of FC. This should give you two tests up to twenty.
