Hi all, i recently bought an MH light from a fellow reefer here. It has a 150W 14K bulb. My tank is a Red Sea Max 130. I tried the lights and found that is not as bright as i have expected, in fact the built-in T5 is brighter.
I assumed the MH takes some time to "warm up", but after 1 hour although the bulb heats up and is very hot, the light is still quite dim.
So my question is
1) Is one 150W 14k bulb enough for 1 2ft tank?
2) Could it be that the placement should be directly on top? Since i was placing it slanted resting on the hood when testing
3) How long does a MH bulb last? Maybe it is due for change, i think it is a year old.
