Just an FYI it took my pool at least a week to get to the color it is now (blue). It was a mirky green for at least a week.
Since you have screenlogic, I would just abandon the spa side remote all together. I know you already paid for the controller and have it installed, but working your spa water level around a device that your phone can easily and better replace is never a good idea..
Sorry that you've had such a bad experience. Just because many people have bad experiences with pool builders, doesn't mean that they will have a good owner builder experience.
Have you noticed any change in the water color?
It looks like you still have a good amount of plaster dust in the pool. Once that is gone, I'd imagine the color changes yet again.
