I'm interested in your thoughts as to if you think this could work.
1.) I have iron in my pool. The plastic white step entry into the shallow end is entirely stained, the white plastic fittings are stained, the filter basket, as well as the deep-end "Joints" where the bottoms meets the sides.
2.) Since I see these stains, does this mean that ALL (or at least MOST) of the metal is NOT in solution? (Basically, has it all "settled-out" and caused the stain?)
3.) If so, if i were to somehow use an Ascorbic Acid to scrub a section...while ALSO simultaneously using a suction hose to remove the water right above the area I'm scrubbing (basically to hover over that area). The hose would remove the water completely from the pool as waste.
4.) Would this then pretty sufficiently remove the metal form the pool? I realize some of it would still be in solution, as you wouldn't be able to vacuum it all out as it was being scrubbed. But would "MOST" of it be removed?
Just wondering if I can rig-up a device that scrubbs using ascorbic acid, yet also sucks out the water that it scrubs. And wondering if this is a viable solution to just using ascorbic acid and putting the metal back into solution (only to re-settle, need to be treated with sequesterant, etc = lots of $)
