Random Vodka/Sugar Dosing Question about Copper and other heavy metals

I sat down and spent some time working through the cycle and possible interactions of both sugar and vodka. Sugar seems likely to promote initial bloom but that bloom may die off quickly from once a day addition and provide the foam skimmate everyone notes with this treatment.

The ethanol addition seems to have a more extensive pathway as it potentially feeds multiple levels of bacteria that may take days to go through the entire cycle.

One thing I noticed though was the ability of anaerobic bacter to utilize heavy metals such as molybdenum. Then PBS aired a special on copper use in heme equivalent in crabs.

Could ethanol dosing sequester harmful reef heavy metal contaminants such as copper by some yet unelucidated pathway? Or is one already known? Or am I thinking way too much into this and should just add vodka and keep my random thoughts to myself?:D
 
i have heard about sugar/vodka dosing, but from what i am told, once you start it u cannot stop, resulting in a system crash if you did stop..but i dont know much about it or if this id even true. its just what ive heard.
 
I guess the simplified question is whether the bacteria that are driven with carbon sources take up significant heavy metals, and what proportion of them are actually removed by skimming (as opposed to staying in the tank). I've seen no data on copper or other heavy metals in the skimmate when using carbon sources.

Copper may be used to small extents by many bacteria, but I doubt they are a big user. Still, I expect some consumption, just as macroalgae and other organisms also reduce heavy metals. :)

I discuss heavy metal export methods here:
