You can use DIY CO2 for a bit to see whether or not you want to make the dive into pressurized CO2.

However, as you are already aware, DIY CO2 may not be the most effective way to get CO2 into an aquarium that size.

Flourish Excel will work as well, but again, is less economical than CO2.

As Excel is not carbon dioxide (and is a carbon dioxide alternative), there is no way to measure its presence via a drop checker.

BBA is black brush algae, a different type of algae.

This sounds like the hallmark of blue green algae (cyanobacteria). It is slightly toxic (i.e. if ingested by fish) this is why most fish do not bother picking at it.

You can remove it manually with no problem (though it may come back very rapidly unless the root cause is addressed).

I am not sure if Excel treatment on BGA will help; it is generally used for BBA.

No, I only have a chemistry minor (I have a Master in Microbiology and Immunology and work as a research associate)
