did u change the bulb when it belw out, or do u change every couple months?
Blew out.
I'd be careful on a 12 gal, it will cook your water. That 50 gal ST tank has a 30 Trash Can(Fuge), 75 gal tank, 10 gal (fuge) and sump that has probably 30 gal in it all tied together. The heat from the 500 W is spread over a bunch of water. Each of the other items listed have lights, but the 500W at the distance you see it from the tank makes the top edge warm, but not hot to the touch. Just measured it, 17.5" from glass to top of water.
I wouldn't put it on your 12 gal. Same goes for a 400W MH in the correct K range as this is the closes to compare to.
