Which ones? The g3 pros?
I just find that halide seems to grow the coral evenly and rounded without a sparatic pattern. I also find it easier to deal with. Probably because I don't feel the need to tweak it constantly. The growth and color with the g3 was ok but too much floressence vs true color of the corals... But the growth with the halides is just faster... The biggest reason though for switching back to halides though is I like the look a lot better, more natural. Another major major reason is that the support and customers services I get from dave at Hamilton technolog is 10000% second to none. Guy goes out of his way exponentially every single time.
