I am new again.... I had a 55 gal that was I thought pretty successful minus the algae issue. Then downgraded to a 20 gal with a clown, 2 turbos and one mean as all get up damsel. Been up for about a year. Due to finacial strains... getting married havent gotten back to starting up a 55 the right way...Anyways I want to do a 50 or 55 gal tank preferably a cube shape or corner tank. My question is about the lighting and the change in lighting. Few years ago MH were and may still be considered the best as far as I could tell. But Radion has new LEDs gen 3 and was wondering for a 50-55 gal setup with some fish and corals(polyps, xenia or mushrooms) what would be best? The LEDs are expensive, but are they worth it and are they better than MH for a 55 gal setup or would a T5 or compact be more than sufficient? Prefer to spend less than $500 on a light but again if the new top of the line LEDs or MH or T5 are worth it I can rationalize and convince the wife.
