THINGS ARE IMPROVING!! We can see the bottom at the shallow end and we can see the light in the deep end. The water in the deep end is still green but a much lighter shade. We have been testing 2X day, using the pool calculator and brushing frequently. I do have a concern. There is a green line all the way around the pool at the level of the top of the light. The swamp water was at that level for at least a week while we waited to see if the repair to the leak at the light actually did the job. My concern now is that the fiberglass is rough from that line down into the pool. The hose of the polaris and the polaris itself is coated with a rough grey green substance. Have we ruined the fiberglass finish?? Is this scale?
