Ive been running the 250 watt 20k/20k dual arc over my 58 oceanic for about a month and a half, and so far I like it. I need to steal Jeremy's apogee and bring it home for the weekend to get some numbers, but everything in the tank is happy with it.
Im waiting for the 10k/20k to show up so I can swap out, and see what difference in growth there is.
