Decided to leave the pool uncovered this last winter. All the leaves were off the trees when I closed, so there isn't that much debris in the pool, just a lot of wind blown dust and dirt.
Pool started to turn a bit green, so I stuck a sump pump on it's side in the still ice covered water two weeks ago. Added chlorine to it, and now just have a cloudy muddy mess to clean up.
Firs test today showed I had 2.5 ppm chlorine left over from my addition.
Filling the pool now. Enough water in it to start the pump, suction through the vacuum port.
Now to get my heater going. rebuilding it this year, and will be posting pics and explanations as a go along, for those who are interested.
Here's to a great, trouble free season!
