Question for everybody, how much difference would 2 T5 bulbs make? I would kind of like to bump up the light a little on this. The ethereals do ok, but even after bumping them up after testing they could still use a little more. I like the thought of going hybrid but with an 18" tank and 9" wide lights my options are limited. I've looked around and I could fit two of the single reefbright t5 figures and hang everything under a kind of floating canopy. I originally thought my t5's were giving me the electrical problem but have since figured out it was the breaker.
