I have a 12'x24' Doughboy pool with expandable liner, 9500 gallons total. I also have a winterizing problem that becomes a Spring opening problem. In this area we have long, cold, wet Falls in which the leaves fall over an extended period but the water doesn't freeze until late, and very suddenly. Short story I need to come up with a closing routine that prevents large amounts of wet leaves and nasty water either on top of or underneath the winter cover and allows me to treat the water until close to hard freeze, but that's for the Fall.
Right now my issue is opening. The pool is green and free of "big stuff" but with large amounts of small particulate matter, too small to catch with a net, too easily disturbed to stay in place while vacuuming, and too heavy to get up to skimmer level without constant stirring. SO, what now? It has been suggested that I pump the whole thing out and refill. Can I do that safely with a 6 year old liner?
