Another how much light question?

[John >]

I just purchased an 850g aquarium that is 3' 6" high, The fw.misc group
thinks that the "watts per gallon" rule doesn't count in an aquarium of that
size. I think my biggest concern is the height of the tank.

I plan on growing average Wisconsin Pond weeds (oops) plants. Milfoil (not
eurasion) Hornwort, Cabomba, Anacharis, Duckweed, possibly even a few water
lilies.

I plan on starting with about 440 watts of fluorescent lighting. High
Output T12 fixtures with Cool White bulbs (don't know the numbers).

Any idea's, comments, suggestions invited!

I'd go for T8's - 30% more lumen output I believe.

Sort of. More like the same light for less watts. Almost the same anyway,
depends on the tube.

I'm still coming to grips with the idea of an 850 gal tank. I think I'd
use sunlight or a 1000W MH bulb on a light mover. Or both.

To grow Cabomba?!?

Underwater lighting needed!

Speaking of lumens, you might want to actually find out how many lumens
hit an "average Wisconson pond" and use enough light to hit that
intensity. A photographer can probably help with light measurements.
Then collect your weeds from around 3 feet of water. I'm with Richard -
I think you'll need MH or sunlight. A Solatube installed over the tank
would be spectacular. http://www.texassolatube.com/

Now I could have had a purpose for the metal chimney flashing that used to
be right were the tank is now. Many years ago there was a fireplace there
and I paid to have the chimney removed. I wonder if the guy could bring it
back.

The High Output fixtures are 30% brighter than standard T12's. I made a
mistake, the HO lights are only the same diameter as T12's, not the same
power. This is 600% more light than the 120g tank with standard hood lights
that I am taking out.
