Personally I've used 4-F40D's in two $9 shoplights with great results in a
planted 55 tank for several years now.
BTW, what's this T-8 lighting you were refering to? Is it the same as the HO
and VHO I've largely decided against even looking into due to cost?

My understanding is that sandblasting grit size numbers refer to the diameter
of the particles in mm. Thus #1 grit is aprox the same as your #18 Sieve Size
and #2 grit is aprox the same as your #10.
After a year-long search when preparing to set up my planted tank, and requests
to over two dozen sand and gravel yards, I finally found the "mythical" #1
grit I was told to use. It is certainly not 1" in diameter, but is a rather
not yet dust like, grain size. There is a certain variability, but not much.
it finally cost me $10 for a 50 pound (~23 Kg) bag. (But then, I'd probably
over $100 in gas, postage and phone calls alone to locate it!)
I layered this over a mixture of soaked vermiculite and dirt. No additional
was necessary for over a year. When algae over took the tank, I added 25
and when they failed to get the algae under control, started using
spikes pushed well into the substrate directly under the largest plants. Now
there is a
little algae, but the plants are back to growing well and I just had a
couple of swords
send up flower stalks and am thinking of setting up a small hydroponic
system to start
the seed pods for maximum germination.
Anyone have any thoughts on this last part?
