Are you wanting to use cable to hang it? we could do something similar to what I did for the light rack on the 750

Don't know if it would help or not (your light is at least 4 times heavier then mine) but I have the cable hangers for my light that I'm not using

I can't remember it. How's it hung?

Might be worth looking at anyway. I'll stop in soon and have a look.

Thanks for the offer but I plan on having this baby hanging long before then.:biggrin:

Thanks Brad. Can't find that size in the on-line catalog, which doesn't necessarily mean they don't have them though. I'll check them out next time I'm in the city.

Ok, I'm finally ready to hang my new light fixture, but before I actually start drilling holes in my ceiling I have a question for those of you who have run 400W lighting before: How high above the water surface should it be hung? (I'm thinking about 12 inches?) The tank is 72" x 24" deep and 30" wide. (mixed reef) The fixture is a 72" Sfiligoi Infinity XR4. It currently has 3x400W Giesemann 13000K Megachrome MH, and 4x6400K T5's and 4x actinic T5's, and 8x LED moonlights. Wattage will increase from 942 watts currently to 1662 watts with the new fixture so I will start acclimating the corals with a one hour on and one hour off schedule, gradually working up to 8 hours of MH, and 12 hours of T5. Most of the corals can be moved fairly easily and the large GBTA will most likely move on his own if he doesn't like the new lighting. Any advice and suggestions are appreciated.

I hope you are going to give BC Hydro a little bit of advance warning before plugging that baby in. I wouldn't want you to overload their turbines or anything .

Yeah, 400-watters will suck the juice I'm sure! I'm hoping the extra wattage will mean shorter time the MH's need to be on though, so the hydro bill might not be too bad.............. I hope.........

Apply a good sunscreen and wear sunglasses before turning it on :lol:
