I read Pool School, the wiki, and several posts on winterizing, but have a couple clarifying questions:
- CYA is very low. Should I bring it back up before closing, or wait for spring?
- I have one skimmer and it has a hole for the main drain and a hole to the pump. Is a gizmo only meant to be used on the pump side, not the drain side?
- In this video, the guys don't lower the water level below the return lines but use PVC pipes so they can access the line above the water level. I like the idea of not getting rid of as much water. Are there good reasons I should not do this?
