lol well if your actually going to pay someone to close it, it should look absolutely clear when you pull the cover off. Maybe you could tell them you want a clear pool guarantee on opening....
closing a pool is i personaly think, and i am about to find out, not really that difficult. I close my pool and it wasnt difficult to learn even without TFP. I am actually just starting my closing pool research since I am now 'in the industry' lol love that title...and would like to learn about closing all pools for my employer. I believe, its mostly about the equipment and protecting it from freezing over the winter, ie getting all water out of the lines, and adding rv antifreeze to lines that will, no matter what will have water left in them.
Each piece of equipment came with a manual and that manual has instructions that include how to winterize it.
People FEAR(False Evidence Appearing Real) closing their pool themselves and wrecking something that costs 'thousands of dollars to fix', verbatim what a customer told me yesterday btw.
With a little effort and TFP you would be very able to close your pool properly.
