OK, so I recently picked up a 12 gallon JBJ nano cube... it came with a PC fixture which will need to be upgraded. Some of you may have seen my post requesting a HQI light for it... here's the thing: When I originally made the request, I was thinking the tank may have been a 6 Gallon, so I was thinking that a 150 or 70 would work. I now know that it is a 12 Gallon, and am wondering if 70W HQI will be enough (It will be primarily SPS), or should I go for the 150? I really don't want to cook the tank, so if I can get by with the 70, good. Any input greatly appreciated, thanks!

You don't think that will be too much heat for the tank?

If you have the 150W 6-8" above the tank it shouldn't be too bad. If the temps do start getting high have a fan blowing across the tank between the fan and water. An auto top off unit may also be required as it doesn't take long to evaporate enough water from a 12g tank to change the salinity on hot days.

I've got a 150watt over my 18 gallon... and I can't keep my heat up enough with my little heater... seems to have no effect what so ever temperature wise. its about 6" above the surface of the water.
