Well, we're on the lucky side when it comes to the pool I guess. We have a 24' above ground. We use it. We love it. We got it used for free and it lasted about 15 more years. We liked it so much, that when the steel sidewall started rusting out badly, we bought a new one on clearance in the fall and put it up in the spring. We've been on that one for about 4 years now. About 6-7 years ago, we converted to salt water. Man, what a difference. The salt water chlorine generator means you NEVER have to add chlorine on a regular basis. Only if a possum dies in the pool or a baby poops its diaper! YIKES!

Then we just dump in a gallon of regular cheap old bleach and its good to go. The salt level is 3300 parts per million, 10 times less than the ocean and about half that of human tears. You feel nothing when you open your eyes underwater, and your skin feels soft when you get out of the pool. Your swimwear fabric doesn't wear out like in chlorine, either. Salt never evaporates, so you never have to add salt during the season (like you do with chlorine), unless the pool gets heavily diluted by lots of rain. Then its just a test strip, a chart, and $2.00 worth of salt.
To summarize:
In spring, top off pool water.
Remove winter cover.
Vacuum dust.
Add 4 gallons of bleach for initial sanitation.
Test salt level.
Add a bag or two of pure water softener salt.
Add CYA (chlorine stabilizer) so the salt water chlorine generator doesn't have to work too hard.
Turn on filter and salt water chlorine generator.
Enjoy for 3-4 months.
Vacuum once a week.
Test chemistry once a week.
Turn off everything in the fall.
Add 4 gallons of bleach for winterization.
Put on winter cover.
Drain plumbing.
Go ice fishing.
