How could I refuse a nice request like that?  Heck, I'll go for ALL the points!

Umm, what is there about a fluidized bed filter that you think will lower your 
general hardness? FBFs are used to achieve maximum biological filtration in the 
minimum space. I don't think it will reduce your general hardness (calcium and 
magnesium ions).

2" or 36" inches of *water* won't reduce the intensity enough to worry about 
what spectrum of light to use. The problem with deeper tanks is that the foliage 
from the taller plants blocks most of the light for the lower plants. Changing 
the spectrum won't help this at all.

OK, I get it - it's April 1st, right?  An April Fools question and I'm IT?

None that I can think of.
