I'll start with i'm sure this has been asked a 1000 times but, i'm starting a new bigger tank, it's a glass 180 gal. 72''x24''x24'' it will be a lps & fish tank. screen mesh for a cover, live sand and live rock, so different mounting heights for corals with the lowest being 22''deep. thinking of some led type, kessil or ai, or something. SO many choices out there, and not sure which i need. i would like the programmable type to do ramp up/down and nighttime, ect. any suggestions are welcome.
