i got a 75 gal . what would enough light to keep anything i want how much is too much i have a baulb vho with ice cap and i was think of dropping 2 of the 48 flourents and putting in mh not shure of watts
check maast.org there is a very recent thread where someone mapped out several MH systems for cheap..check it out. its titled like "125 gallon lighting" or somethin like that
Ditto what Reaper said. I had 2 x 250 DE bulbs on my old 75 - was more than enough light. My only complaint is if you are running open top it may be hard to work in any additional actinic bulbs so you may want to look into some of the 13k, 14k or even 20k bulbs.
I'm open top. I run 20k Radiums and use 2 actinic T5 tubes for morning/evening viewing (on a timer). I would show you my tank but my camera cannot take shots under 20k MH :?:
