Right now I have a 130 watt, 50/50 and actinic, and a 70 watt mh
pendant behind the fixture. I want to upgrade the lighting to only metal halide and was wondering how many watts to go with. Since I have a 29 gallon, the dimensions are a little strange and am most likely going to with a pendant (since most combo fixtures do not fit well on the tank). Anyway, what spectrum and wattage should I go with. I was either thinking 150 or 250 since the price does not jump to bad between the two. Another question, is there a difference between going with a double ended bulb and a screw in type bulb? Does anyone have a specific brand that is good? Right now I have been looking at the hamilton pendants at 20K, since their will be no actinic supplementation. So what do you think, 150 or 250 and is Hamilton a good brand? All of my corals are bascially LPS
, but I would like to add some acros, clams, and/or neon colored ricordea's or zoos. Opinions? TIA............
