Reflector.
Hi Dwayne,
I have the same size tank..36L x 18W x 21T and I ran my 250W MH perpendicular to the tank. I made my own reflector with white aluminum sheet metal and bent it up similar to the store bought reflectors. (I am going to make one out of polished-hammered aluminum when I find it)
Right now I have two 3' NO actinics at the front of the tank. In the near future I am going to add a third actinic and make them all VHO or overdriven.
My MH reflector is 13" long and both actinics fit in the front fine (even tho my hood is angled at the front 6 inches)
The third actinic will have to be screwed to the back of the hood on the vertical, just below the MH socket.
Apparently, it is better to run your MH lamps perpendicular to your tank if you can...so I heard.
I wish I had a camera or could draw you a pic of my setup.. [img]images/smiles/icon_wink.gif[/img]
