    This yrs numbers and a few questions

    Todays readings:

    FC 2.5
    CC 0
    TC 2.5
    PH 7.6
    TA 50
    CH 60
    CYA 25

    Water is cloudy/blue. LOTS of pollen this year, rinsing sock as often as possible. PH has stayed in 7.2 - 7.6 range, am I ok to leave TA at 50 as long as I maintain that ph range. And, cya is probably closer to 20, should I bring it up with the (hopefully) increased sunshine?

    Gotta work the next 3 nights so I plan to do an overnight FC loss on thursday night and if it is off then shock, if not continue to try and clear my water with the sock and vaccuming.

    Thanks for any advice!! (Gonna add bleach to get my FC up now!!)

    Those numbers don't look bad at all. I'd probably bump the FC up a bit since your water is cloudy. The TA is ok if your pH isn't jumping around. If it starts being a problem you can bump it up then. I'd want more CYA in there than 20 - 25 but your chlorine usage will be the best determining factor in that. I'd suggest starting at about 40ppm CYA.
