Hello to All,
We had our pool plastered and pebble-sheened in late Jan this year. The color is Irish Mist.
The PB maintained the pool after start-up for 2 wks, then since I was traveling a lot, I hired a pool maintenance comp that has been in business for 28 yrs. There were referred to me by someone that had very good results. They have shown up on time every week and text me the water readings per pH, TA which were high at first but have been much more closer to ideal lately. On 4/23, pH 7.6, Cl 3.0 TA 90
I registered the P-Sheen w the installer and they are coming out this Wed. This is not scale per the pool maintenance comp, but discoloration in patches and on the wall that faces the west. Pool guy called it "not uniform color". The patches are a bit darker. It has also taken place in the spa too, but not as distinctly.
The pool and spa are 15K gallons, 3.5", 4.5" & 5.5" from entry to spa spillover, respectively. The pump is a VSP EcoStart Hayward and comes on daily from 8am - 4pm. Have a cartridge filtering system and water is Cl-based. Have been running the QC Robotics SHark for the last month.
Does anyone have any idea what this is or could have happened?
Either way, what are the potential steps or resolutions to correct the discoloration?
Thank you very much,
