Had my pool resurfaced in March 2015, about May-June seemed to notice color was uneven, blotchy areas, called builder, finely in early August he came out took pictures and (6 months later) returned today along with the builder was the gunite/pebble supplier and the owner of the crews that did the work....the gunite.pebble guy said that the pool has been over chlorinated causing the pool to bleach out in those areas.
The areas have not gotten any worse since May-June...just looks kinda blotchy not an even color (will try to post pictures).
I am not trying to get something for nothing here, I made it clear with the builder, if this was any way my fault I will pay to fix it, I need someone here that is familiar with this type of problem. Makes sense maybe me trying to hold my Chlorine high because of high CYA created an additional problem of bleaching out the pebble color.
I also want to say, yes I am very aware of high CYS reading, before this coloring issues, plans were to get the CYA back down to a more reasonable number, my fault as I started using tabs, until I was educated by you guys and switched to liquid....
During the summer with water temps at 90, I tried to hold my readings @ Tested every 1-2 days
If anyone can give me insight here would be much appreciated...thanks
