Welcome to our forum.
... I see a drip from a tube on the right front bottom of the spa. ....
I called the guy (not Andy) and it turns out the drain valve was left open... I turned the red valve shut and will watch to see if all the puddling stops. He had no idea about the flakes.. said he had just swirl treated it himself and the water chemistry had been kept up all along... very weird. I will try super shocking with dichlor and hand skimming the flakes every day, any other suggestions? I appreciate everyone being so helpful.
