Oh to hell with pools. I have a pool at my vacation house i use only during summer and god damn is that pool a pain in my ass. When i built it, i thought it would be a cool thing to have, chilling by the pool, drinking cool beer.
HELL NO! Every year before summer i have shovels of fucking frogs to throw out. Their shit and tadpoles stuck to the tiles. First you need to get rid of the shit filled, tadpole filled rain water using a bucket since the pool pump wont pull the water out if its not filled to a certain level. Then you collect the damned frogs and throw them out because the stupid bastards only know how to go down the steps in the pool but cant get up the stairs for some reason.

Then you fill up the pool to 1/2 and throw out the water, then fill it up again, add the chemicals you need, and once thats done you can use it....
But still, you have to be there every few days to clean the skimmers, backwash the filter if needed, check on the chloride levels in the water, PH, etc or algae starts showing up, and when you have 30 guest vacation house capacity, with temperatures of 35 celsius plus during August, and kids start pissing in the pool, you must be on constant watch that the pool wont turn green...
I cant explain how much of a pain in the ass that is.
So yeah:
