do you need to dim the royal blues? i was thinking about this since royal blues are generally actnincs? you can save 20 bux by not buying the dimmable drivers.

I do not. Unless you built your fixture with to many blues to start with, there won't be a reason to unless you want to tweak the color. FYI, I built my lights with the Meanwell non-dimmable 700 ma drivers.

i have my led's set up in two different strands in a 29bc. one all blue and one all white. the white ones i have dimmed at 40% and the blue ones at 50%. should i be worried that i will start bleaching out my corals if i do not dim the blues?

i was gonna start another light fixture for a frag tank and i wanted to swap out one of the dimmables i have for a non dimmable to save 20 bux.

Just use half as many LEDs, or run at a lower current.

But to answer your question - if you're currently running your blue LEDs at 50% and it is appropriate for your corals, I would be very worried of problems if you suddenly jumped to 100%. Another user recently posted PAR test results that showed that royal blues produce similar PAR as cool whites, which would lead me to believe that the intensity "felt" by the corals depends on the intensity of both colors of LEDs.
