    More shocking after winter closing?

    I still remember the trauma of opening a "green pool" in the beginning of the 2008 season. Well, it wasn’t exactly a "trauma", but it wasn't the best pool experience, to say the least.

    It happened because snow and rain over-filled the pool above the winter cover and in early spring the leaves on the top started the algae bloom.

    I prepared a counter - measure by immersing two pumps in the pool. If and when I notice water reaching the cover I'll pump it out.

    Nevertheless, I wonder if it makes sense to continue to monitor the FC level and to shock if necessary. In order to get circulation I'd use the pumps returns (garden hoses) and I am also considering leaving my robotic cleaner inside, to aid in circulation.
    My pool closing shock level was 26 ppm (CYA = 60).
    Any comments? Would leaves and organic debris that may accumulate in the robotic cleaner start an algae bloom?
    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.

    Yes. The little bit of chlorine that might have made it thought the winter will get used up really fast trying to clean the leaves, and then the algae can take hold.

    Does your pool not freeze? I see you are in Mass... Can you open a little earlier (while the water is colder) and get the junk out of there?

    "Shock" is a process, not a product!

    In the winter, just a couple of inches at the top freeze for a month or so.
    As for the leaves - this is really a small amount because I cleaned up almost everything before closing and covering.
