I've got a fiberglass pool that's right on the edge of a marsh. They had a tuff time digging the whole because it kept filling w/ water.
I've got recurring problems w/ iron staining on the fiberglass. I'm getting set to go w/ the Ascorbic acid treatment, but was wondering if I might get a head start by partially draining the pool to reduce the iron concentration in the water.
Among other sources, I've used a long rusted snake to try and clear my skimmer line.
1. Is this a good theory...to reduce the iron concentration. Will it make a big difference?
2. How much can I drain the pool before it becomes hazardous to popping out of the ground?
