I was successful with VHOs on my 125 and I only upgraded to halides for the glitter lines. The color of VHOs, particularly URI bulbs, are the best IMO.

No. Watts are watts no matter what(that's a mouth full). 500watts of MH are the same as 500watts of VHO when the bill rolls in. Like I said I only got them to get glitter lines, but that is a personal choice. Halides will reach further into the tank and generate more heat. So, if heat is an issue MH may be a problem that would either need a chiller or more fans to eliminate or disperse heat.

I have a 24" deep tank, a 65 gallon, and I use 4 24" VHOs (75 watts each). Everything is quite happy. My torch and frogspawn have grown nicely, and I had a hitch-hiker plate coral which was the size of a pinhead and now is the size of a silver dollar. The mushrooms have actually dropped off of the high rocks and sank to the bottom.
Just be sure to use 2 blue actinics and 2 of your choice. I use 2 blues, 1 white actinic and 1 Aquasun, all URI. |

i had 4 110watt VHO bulbs on a 24" tank ( 120gallon 4x2x2 ) and kept what your talking about no problem. i would go with 2 actinics and 2 50/50's bulbs, it looks good with that combo. good luck.

If you want clams or SPS just keep them on the top 1/4 of the tank. I kept my maxima clam(which I still have) and a seriatopora(sold) under VHOs without any problems.
