OK i just purchased this lighting system
http://www.aquacave.com/coralvue-400w-double-endedbrhqi-metal-halide-retro-kit-1193.html
I have been trying to light my 54 corner but have been having trouble with my 24" MH/PC combo light ebay brand due to the small reflector and overall shape of the light in comparison to tank, so decided to spring for this one.
It was fairly reasonably priced, and a large reflector to help me get the majority of the tank with quality light and the 400 watt de would help me to get the depth of the tank.
One of the only things is they only offered a 10k or 20k bulb, so I opted for 20 because I am not going to be running any supplementation and feared 10 might be too yellow alone. Will this be ok as far as PAR go's for SPS growth, and does anyone have any experience with the coralvue 400 watt 20k DE HQI bulb? And will 400 watt bulb make a major difference in comparison to 250 as far as heat goes? (sorry for multiple questions, just a few thoughts on my mind as I prepare for it).
Any advice would be appreciated, it should be arriving in a cpl days and at that point I will be selling my 24" MH/PC light and it will be posted as so.
