There is no known positive role for aluminum in biology. There are
suspected negative roles. Therefore, I see no reason to have it in
contact with aquarium water. I don't have problems with anodized
aluminum reflectors, or other incendental contact. I would not put a
piece of bare aluminum in my aquarium, though. There is no reason to do so.

That is way too much money for an aquarium lamp. You will be better off
with an industry standard triphosphor lamp. I doubt that freshwater
tanks need such a high color temperature light source.

It makes some carbon dioxide when bacteria use it.

That isn't true in marine systems, and I suspect that it isn't true in
freshwater systems, either. Most photosynthetic organisms are quite
competent to pull glucose out of the water. The question is whether or
not that does a bit of good. And whether or not the target organisms get
it before the bacteria.
Gluconate is a potential iron chelant. As is fructose, actually. There
is more to the product than just chelated calcium. For all I know, it
does have some positive effect on freshwater systems. I have not done
the experiments to prove otherwise. However, I don't think that
freshwater tanks are generally short of dissolved organic compounds, nor
potential iron chelants, so I do have some reason to doubt its efficacy on
