    Duncan coral?

    Corals grow in the direction best suited to them for that location. I wouldn't worry about moving them.

    ATI Bulb bad??

    I call BS. I have 39w ATI Purple Plus and it, like all T5's, fires instantly. Try swapping in a different bub or moving the bulb to a different ballast to rule out a bad ballast but I'd say probably a bulb issue.

    How do you know when to change bulbs??

    It's tough to tell with T5's unless you have some way of measuring light ouput such as a PAR meter. Depending on daily use, 12-18 months should be the minimum. Watch for shifts in colour spectrum, light intensity, undesirable algae growth or slowed coral growth all of which may be an...

    CPR HOB Refugium?

    I have a medium on my 65 gal and the chaeto grows well. I've also got some caulerpa racemosa in there, although not be choice, that grows ridiculously fast along with a 3" sand bed and some bits of rock rubble. I'm sure it does help to control nitrate and to some extent phosphate, but more...

    MH,Cebu Sun

    I've been running the Cebu Sun for almost a year now. 2X250 MH and 4X39W T5. The only downside is the lack of individual reflectors, but other than that it's a great unit.

    Halide + T5 Fixtures

    +1 on the Hamilton Cebu Sun. I have the 2X250 MH and 4X39W T5, 36" fixture. Good unit.

    2x250mh and 4 65watt is this to much for a 55g?

    I have 2X250 MH and 4X39W T5HO over a 65 gallon (36" long.) No heat issues and all corals are doing well.

    LIGHTING question: Do I need to supplement my 20K MHs with actinics, or??

    You shouldn't need to with quality bulbs, but you may want to for added flexibility. I run 2X250W Hamilton 14k with 4XT5HO (UVL SuperActinic, Purple Plus and 2XHamilton Actinic.) I use the T5's for dawn/dusk and find the Purple Plus gives my reds/pinks a nice pop. If you've got the room and...

    how about Hamilton Techonology's lighting system

    I've got a Hamilton Cebu Sun fixture. It's built like a tank.

    Why? Controller vs. Tunze ATO

    I top off with kalk but switch to RO/DI if the pH climbs too high; pretty easy to do with a controller.
