I know on the surface the answer to this question seems quite obvious. But I am following another member's thread regarding Mustard Algae coming back year after year and it made me consider the question:
If I have hidden algae when I close the pool for the season is it possible for algae (be it green, mustard, black, red, purple, fuchsia) of any kind to survive a northeast winter?
Pool is always closed with perfect water balance and FC brought up to Shock Level using liquid Bleach. Cover is a safety solid. 100% solid. Not mesh, not a permeable solid. This is a heavy vinyl cover that allows zero light to pass through. In the absence of any light, being subject to freezing temps for months under the cover, and blasted with a 30+ FC upon closing, is it reasonable to surmise that no algae can survive and I should theoretically be opening to an algae free pool every spring?
