Ever since the pool was filled, 2 months ago, I noticed yellow patches where the floors meet the walls and in corners and other areas. I can only see it in the morning or at night when there not too much sun. I mentioned it to the pool builder and the only way they could remove it was to use a metal wire brush. When I looked with goggles, it looked to me like the area had not been worked enough when the plaster material was applied and so you can not see the flecks of colored aggregate as much as you can in other areas - so you see more of the white plaster on the surface which appears yellowish and has a slightly different texture. Has anyone ever hear of this? There are some more areas that the pool builder did not fix and I was debating on whether I should use a metal bristle brush or try pumice stone? When I checked with goggles after the metal brush was used - the surface was no longer yellowish - but it seemed to me like it was a little darker than the rest of the pool - I wonder if the metal in the brush had anything to do with that?
The chemicals in the pool look good - although the PH is running high and so I'm getting a handle on that - just got the TFTestKit yesterday - I have 3 copper Scupper water falls...so aeration may be the culprit to the high PH.
Thanks for your input on how best to deal with the yellowish areas...
