I've been doing saltwater for a couple months now. I have a 14 gallon nano with a couple clowns and a 45 gallon many leather, Lps and sps corals and a blue crocea clam. A handful of shrimp and other inverts, a neon dotty back, couple small gobies, coral beauty dwarf angel, small yellow tang(temporary home). I am also starting a 72 gallon reef tank, but I'm trying to decide if a couple ecotech radion fixtures or a metal halide combo would be best. I just think the halide would he the room it's in too warm and draws considerably more energy and money in the long term. I'm just concerned with the radions not growing sps acros and montis like I have going in my current tank which is set up on a 6 bulb t5 fixture. The bulbs in that fixture are aquaticlife. Are these ok or should I upgrade to a better bulb set to get more growth out of my high light animals? Also, for the 72 gallon set up I will be running a p1200 sump and separate refugium. Are these good? I'm running a p1000 on my 45 gallon with live rock rubble instead of bio balls and it seems to work fine, I even have a small led light and some cheato in the center section. All my levels are good.
