I live in the northern US and have had my 125 setup now for going on 2 weeks.
The canopy the previous owner built using individual reflectors on each halide lamp (3 MHs) He also, differentiated the halides. the end Halide bulbs are 250W each, and the middle one is 400watt each. The person that had the tank before me, has his scheduled printed and taped to the inside of the stand next to the reef keeper 2.
From 1- 5 PM he had the single 400watt Halide on. At 5:00pm he shut off the 400 watt bulb and ran the 2 250s from 5pm to 10pm.
The 2 VHO bulbs he ran the entire time. 1- 10 pm. His reef did great, as I got most of his corals and they look healthy and awesome.
In the any exposed wood in the canopy is covered with a thin reflective material. or Painted with reflective paint. Not sure which as it's paper thin, but covers everything in reflective silver, even wires were covered with this.
Then to assist with cooling the bulbs, he spliced in 1 4.75" square fan on each end of the canopy. No typical fan though, He used computer case fans. the wiring failed on me i the first week of operation so I had to wire in two brand new fans. But they're awesome. They're ball bearing fans. Operate around 2100+ RPM. And consume such a tiny amount of electricity they could run all the time. I have those plugged into the reef keeper temp control so, they only run if the water gets warm. It keeps the water at a steady 79.
Running the halides only 9 hours a day at 400 watts per hour or 500 watts per hour, should save electricity and keep the tank from getting too warm. And save on the bulbs, making them maybe last 14 or 15 months instead of only 12.
I haven't gotten my first electricity bill with the halides running, but I'm hoping it's less than $20 amonth. lol. And all the thermostats for my house are in the tank room now.
I think this is going to be awesome!
