Hi all. A friend of mine just got back ICP results which showed elevated levels of aluminum (185.00 ug/l) They suggested remediation. I suggested that GFO would work to remove/absorb the aluminum. (where the aluminum is from is a whole other question) The question then became how much GFO to use. He cannot use GFO indiscriminately as it will, of course affect his phosphate levels as well as Aluminum. Most of the calculators for phosphate removal via GFO only take into consideration tank size and the type/brand of media. The only calculator i found that takes into account how much media to use, based on current-to-desired phosphate levels, is the RowaPhos calculator. So that is a good starting point. My questions are (a) to use that particular calculator I would need a comparison of other GFO media (High capacity, regular etc.) to RowaPhos. (b) does anybody have an address to such a calculator for other brands of GFO? (maybe i should have led with that question, lol). Of course its possible that the amount of GFO used to remove or lower his aluminum will adversely lower his phosphate to undesired levels, but he could always add phosphate, I assume. Additionally (c) is there another aluminum removal method that would not have deleterious affects on other parameters?
Thanks
