Ive been reefing for a while, had a bigger tank back in the metal halide days...this is when t5's were just starting to get on the scene.. I had nothing but great results with mh but the cost to run them was crazy..light+chiller=$$$
So quit the hobby, came back because of the new led lights that use up way less electricity, no chiller needed either. To get to the point, I started my fusion 20 in may this year and over it i have a radion g2, happy with color and growth, nothing like when i had mh, but my pockets dont hurt as much. To all the die hard SPS guys that say t5 is the way, I agree it gives great results but the overall factor needs to be considered (color+efficiency+temperature control) also feel that feeding and parameters is a major part of color..just my 0.2$
