I am planning a new planted tank. It will be the tall ADA (approximately 48 x 18 x 24 tall). I have a 250 watt MH pendent I was planning to use over a corner saltwater tank. Will this work for me over the planetd tank or should I be looking at getting a T5 fixture? If I go with the T5 will 4 bulbs be enough or should I get the 6 bulb configuration? Thanks all for the help.
