I still haven't decided on the lighting side, since my current 35gal is
on
very bright side, 8+W per gal, I just don't feel very confortable with
such
dramatic drop.

8+W per gallon? You are a brave man! :-)

Now I might just go for 3 X 250W HQIs. But then I still have
3 weeks before the new tank is in place, I still have time to think it
over
again.

Hmmm... 750W on 200gal is 3.75W/gal. For my taste, that's too much.
But I there are people who do very well with such high light levels,
so I guess it's possible. How often do you have to prune
plants with your 8+ watts?

Cheers,

Michi.



My 2 cents worth. I have a 140 gal Oceanic tanks (48x24x30). It is 30+
inches tall. There is a lot of light loss over the added 6 inch height. Go
for the more wattage. If you wire them on individual switches you can
always turn them off if it turns out to be too much light. I use 4 96watt
CF. I wish I had used 8 55watt bulbs. You will find that the middle gets
the right amount of light but the sides could use more. Position the bulbs
to give you the better coverage.
