Have you had major problems with your pool builder? If not, I think your letter was a bit harsh. Unless your PB is giving you a hard time about taking care of your issues (and everyone usually has a long list of them), it's not worth getting aggravated about. I have a long list and PB is taking care of all of them. A lot of patience is needed during this process because the sub-contractors may already be working on other pools and you will need to be squeezed in to get your issues resolved.
That being said, another user had mentioned brushing. I HIGHLY recommend finding out as soon as possible whether or not you should be brushing your pool and how often. I am not experienced enough to comment on all types of finish, but my PB wanted me to brush my 60% quartz plaster 3 times a day for the first week and then 2 or 3 times a week thereafter (although I brush every day anyway). Luckily, I am unemployed so I have never missed a brushing. I would also ask about the dogs. My PB doesn't want ANYTHING in the pool besides humans for the first 30 days. He probably would cringe at the thought of dog claws digging into brand new plaster.
