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 
that basis.
