michigan pool, peeked under cover and green already.
we usually open the pool week before memorial day, plus or minus a week depending on the weather.
I Have mesh pool cover which allows some sunlight thru the tiny holes. was 54 degrees yesterday so I peeked under the cover and it is turning green already.
Should I just leave it and worry about it when I open the pool? and will be massively green.
or should I start putting chlorine in so I don't have even a bigger green swamp when I go to open the pool?
was thinking maybe next year I should put a solid pool cover under my mesh cover so it doesn't allow any sun thru, so I don't get green water ever year?
