I have a 35k gallon in ground pool. Man this thing is a ton of work. I would like to leave it uncovered this winter, the cover last year was a ton of work with it sliding in, filling with water, frozen water bags etc... Three things I'm worried about this winter. Keeping stuff out, preventing freezing, and water chemistry getting all jacked up. Can someone write up what I'll need for gear this winter? Pool is surrounded by tall trees, Pines, oaks, poplars... I'm thinking leaf net, leaf vac, and some type of heater on the colder part of the winter. I don't have a robot, but it would die fighting off the amount of leaves that are coming...
