    pH drifting upwards - is it polyquad?

    I haven't opened yet (Tuesday is the day) and meanwhile I keep FC and circulation using sub pumps at 3000 gph.
    Initial numbers:
    CYA 8
    FC 1
    CC < 0.5
    0< Ammonia <0.25
    Alk 90.

    I also added some 60% polyquad. Before I added the alagaecide pH was steady at 7.3 - 7.4, but after that it drifted to 7.7-7.8. Is this a coincidence?
    We've also had some rain but rain here is acidic.
    This is my ticket for Heaven (when all's working..) :
    22k Gal gunite IGP, 38 SF Anthony DE filter, 1 HP Hayward Super Pump
    380k BTU Raypak Natural Gas Heater (Model RP405A) and solar cover
    8 gal Liquidator w/ 12% bleach, Dolphin Diagnostic Advantage robotic cleaner. 3800 ppm salt, 50 ppm borates.

    not sure if it is the poly, but it could be the rain...although your rain water may be on the acidic side, it is a very good source of aeration which could raise your PH.
