Any ideas what may be causing this discoloration in the tile grout? I know many don't like tile grout showing like this but we do - maybe a bad choice? No signs of the same discoloration in the plaster at all and none under the water line. We're still scraping some sticky "gunk" off the tiles.
Just added about 2 more inches of water to the pool this afternoon as well. The water was about 1 1/2-2 inches up the tile line. I don't think this is iron since we have municipal water in the pool but.....
We plastered & filled on the 30th June. Fill came from local municipal water source so it is treated, chlorinated water and not well water. Electric hooked up 5th July then pump, filter started on 6th July. We have had 2 chlorine pucks in 2 skimmers, added some calcium on the 6th and 4 qts of muriatic acid over 4 days.
PB gave us those test strips (waiting on my TFP Test kit to arrive!) and according to the test strips we have:
PH bounces from too high to just right
Alkalinity bounces from too low to just right
Stabilizer bounces from too low to just right
When we had an AG Intex pool, I maintained it for 3 seasons with BBB and now I'm at a loss. We will be firing up the SWG system in another 2 weeks so I'm nervous to really mess with the water.
Thanks for your input!
