This past year was my first year using TFP methods, and in nearly twenty years of pool ownership, it never looked better. I closed the pool MUCH later than in years prior; hyper-chlorinated and put on the loop-loc mesh cover. Ignored the pool all winter.
A few days ago I peeked under the cover hoping to see clear water underneath; alas, the water is green. Clear, but green.
So, my questions are twofold: what should I have done differently over the winter, and what do I do now? We have never opened the pool before Memorial Day before, although I was planning to open maybe in April sometime. It will be too cold to swim in before June. Do I try to balance the water even though the pool isn't full and pump not running, or do I let it go, clean up the mess when we do decide to open and vow to do better next year?
And yes, I have a good test kit.
