Drain and refill 33,000 gallon gunite pool

[Watermom]

I have been battling green water for over a week. Except for chlorine (which I didn't test b/c I have been too lazy to buy the supplemental kit),

Can't be lazy with a pool or you'll continue the green swamp cycle! Good luck getting your pool clear. Follow Jan's advice and hopefully your pool will look pretty good by Saturday.
