My tank is 750mm high. The sand bed is bout 80mm+- high. Iv got a stack of mixed lebowa, biorock and liverock in the centre of the tank...and the surface of the water is bout 25 - 20cm from the highest point of my rock stack. Iv got D+D aquarium T5 Razer electronic ballasts with a Geisseman Aquablue+ and Actnitic+ tubes of 25w each with a reflector each. They are bout 2ft in length.

Now my Q is.... how many T5 tubes would I need to be the equivilent or better, of a light fixture of 2 MH lights?

I dont want MH because they generate a ton of heat.


Heres an older pic of my setup...havnt update the images yet...just for a rough idea. :

6 high quality T5's would be ample. (ATI or giessmann globes)
If you going SPS keep them high up and they should thrive. T5's also generate alot of heat, its just not as localised as MH's

Well it would depend on what MH you talking about 150w, 250w etc and what T5's 39w 54w. What do you intend to keep, 750 is deep for T5's as they give a very dispersed light.
I spose 150w MH. Id just like to know that iv got enuff of the right lighting for when I upgrade to reef in the future

i dont think 150W MHs would be good for the tank, you would only get decent light up until about 600mm from the water surface, this is ok for softies but not SPS, so i think you should work on the idea of a 250W MH. that would be safer. Mekaeels tank is 600 high and complains that his 150W MHs arent enough for him(maybe because he just wants more, i dont know), but its an idea
