I had an argument with my pool builder early on and as a result, we've had very little correspondence since. In fact the guy I argued with, the owner I believe, assigned his partner to us and won't have anything to do with us after the argument.
Anyway, pool was filled probably 12/18 and he came out when we were at work to start it up. He sent an email saying to brush it daily and nothing further. Kids were anxious to get in it this weekend so I let them, but it was cold so they didn't stay long. I was brushing it daily but there was so much sand in the bottom that I used the vacuum and cleaned it. The robotic cleaner has been sitting in a box in the yard where they left it for about a month so I put it together and decided to throw it in there Yesterday. It ran maybe 4-5 hours with me pulling it and cleaning the filters a few times.
Well now that I found this wonderful site, I see I have made a few mistakes, mainly running the cleaner. Have I done damage to the plaster? Should I mention that I did these things so pool builder can check things or keep my mouth shut?
