My friend recently handed over an older lead Ballast, which can power two 48", 110 watt VHO's.
Eventually, I am going to build a hood for this(and to mount a single 40 watt bulb). My question is though, on my 55 gallon, the regular flo bulbs really don't hit the bottom like they do the top half of the tank in intensity.
What is the "reach" of VHO bulbs? 18 inches...24 inches?
I am planning on raising them (in the hood) above the water somewhat, as he suggested it would be even better to build a very secure hood, and remove the glass so the glass wont filter/block anything for the plants.
He also said the removal of the glass would help cool the water, as VHO bulbs run hot with the ballast he gave me(an electronic would be cooler).
SO, as to help keep the tank cooler, I didn't want them too close to the water.
Thanks
