Well, yes and no. You do have to clean it and keep the water maintained, and it can end up costing a lot sometimes (at least mine did). But pools are nice to have! If you can keep up with cleaning the water then no; pools aren't hard to deal with.
is there a hydrostatic valve in the bottom? These are designed to let ground water into the pool to avert the pool starting to float it way out of the ground. Once that hapens you are in big trouble.
to be in lot of trouble
Put a cover on the pool to minimise sunlight on the water
Keep pumping it out as it builds up but don't block it of you may end up with a pool floating up out of the ground.
YES if you keep water running lol
Pool worms they come from the trees and blow into the pool. Keep up on the chlorine, make sure the levels are right and use the pool cover when it is not in use. The chlorine will eventually kill them and they will be filtered out.
You spray the chlorine gas engine and then scoop up the caterpillars with a pool cleaner net.2You could put something they can't climb up around your pool, but low enough so you can get in.
Yes, as long as the pool itself is on level ground. If not then see if the pool company that is going to build your pool give you some pointers.
They couldn’t keep their trunks up
I'm going to assume you mean the cushions that under the pool cover. They keep the rain water from pooling up on your cover.
Alage grows with light, hopefully you have a dark cover, just leave the pool covered, if you can put some alage destroyer in the pool when ever you think about it once a month or so you should be fine, however the debris that collects on top of the cover that should not be allowed to build up that's where you get into trouble try to remove or keep it off the cover and uncover the pool next year,
Just follow the instruction scoop up the leaves etc and take a sample of water into the pool shop once in a while to make sure you have the water balance right.
