Hi everybody. I am new to this forum and a new pool owner. Well actually, I just remodeled my pool with a contractor who has been a nightmare. He installed a new pebble finish in midnight blue. Its been almost 3 weeks since he has installed the pool and I have noticed these colorations from the first day. He assured me they would go away and to "keep brushing". So far they haven't gone away and I can't really say they have dramatically decreased either which has me nervous.
I read about something similar in another thread and the poster said it was due to a poor job in acid washing the pool after installation. I was hoping to post my pictures and see if somebody could help identify the problem and hopefully the solution...
thanks for your help in advance!!
BWT the corners pictured are the worst areas and i used these areas because they are the most clear examples, however I have this problem on smooth surfaces as well (although to a lesser degree).
