Richard if you are going for T5, get 2 x 6 tube Sunpower units. Either dimming or non dimming. If you want only 10 tubes then get 4 and a 6 tube units. An 8 tube unit with 2xReef brights on either side is more or less like a 10 tube unit.
FWIW, I wouldnt be worried about replacing so many tubes every 8 months...I replace my ATI tubes well into a full year. Scotty runs his T5 tubes like every 16 months or something...and his tank is a TOTM tank.
Thats IF you really wanted to switch from halides...![]()
I'm picking up a used 10x36"power module to add to my growing collection
No prob please jump in one thing I noticed with the t5 I put the fixture over the tank last night for a min is maybe not as bright as metal halides but u can see into the tAnk better and it does illuminate every inch it's over
Which daylight tubes are you running? I use at least 2 ATI Aquablue specials. These have significant spikes in the green/orange/yellow/red parts of the spectrum and consequently brighten up the tank. I also like Richards idea of using a GE 65K tube; it is visually quite bright.
