Metal Halide again

[chris stevens]

Thoughts on this unit? 55 gallon tank, about 18" deep or so (from top of sandbed) will the one centered halide lamp result in poorly lit areas in the aquarium?

Most set up mh's using 1 bulb for every 2' of tank length. 1 bulb centered on a 4' tank will leave the sides noticably dimmer than the center.

tank is 36" - problem?

I'm running 2 MH bulbs on a 5 foot tank and the coverage is just fine for me. I can post a pic if you like. I'm using tube bulbs.

The bulbs are about 14in above the water line however, the closer to the water, the less coverage you'll see.
