I am thinking of doing a MH setup over my 36" cube tank. I am debating going to MH over my 36" cube tank. Looking for either a vertical bulb configuration or a LumenMax (large) reflector. Thinking 250/400W bulb. I would also need a ballast. I want better light distribution than my current LED setup. Prefer mogul bass instead of double-ended. Still TBD if I want make the transition since I would need to build canopy and such.
