My future tank dimensions r 1.5x0.8x0.7 with a water level of 600mm. I would like to know what is the min and max lumens required. Also 3 options, namely t5 or mh or combination of both with t5 as the main source of lighting.

Hi SchyffS,
Firstly, you need to decide what sort of corals you going to keep, Softies, LPS, SPS, Or mixed? this can change things.
Generally, I would say 2x 150W Mh or 8x 54W T5 would be OK. If T5 used I would use maybe 5 white 3 blue, but this would depend on the brand of bulbs used. If you liked, you could increase this to 10x T5, that would be very nice. I remember when I ran T5's, I had 8x 54W on my 1.4(L)x600(W)x550(H), it was awesome, so 10 on yours would be good, even for SPS I recon.
If you go MH, 2x 150W and 2x 39w blue/white, would be fine, If you really wanted to go full SPS then you could convert to 2x 250W.
Mh give a nice "shimmer" effect on the corals that you don't really get with T5's, also the other advantage of Mh is space, I remember when I had my T5 over my tank, I always battle to get into it as it basically covered the tank, where Mh would leave you with some open space to work.
