i ask because my tank seems to prefer (i think) my red channels both turned entirely off and the whites drastically reduced. i keep thinking about toying with the idea of adding some t5 but with an open top there's no way to make that look pleasing.

I'd have to go and look but I am pretty sure I am sitting around 70% total power output on high efficiency mode. The curves themselves are obviously variable throughout the day. I run some of every channel, but definitely on the low end (~25%-10%) for reds, warm whites, yellow. The cool white, blues, hyperviolet, etc all run up to around 80% at max.

I didn't add the T5's due to a lack of PAR, I added them for covering the shady areas the mitras seem to produce. I was just surprise at the actual increase in PAR and how the increase isn't linear in the tank. The lights are mounted at the front and back of the tank though, not through the middle like the mitras, so I suppose I should see a greater effect front and back.

For those that don't know how Mitas light levels work here is a quick breakdown.

First off you set the Mitras unit in either high efficiency or high output mode. I think high efficiency is 70% of what the total unit output is.

Secondly, you set a total output in that setting. I think mine is at 70 or 80%.

Thirdly, you set the total power output of each of the 9 led channels and the times which they turn on and off.

So essentially you set a percentage of a percentage of a percentage.

wow so you are running the mitras pretty dialed back then eh . And your at 9.5 inch above water line.

Well this could explain my bleached out colors lol .. my pink and white red planet..

I have been running 5" above water . 100% high output. With white at bl , rb and white all at 100% . thats way above your settings..

time for me to dial back

thanks !

First one appears to be an Austera and the second a tenuis. Will see more of a difference once they start growing out in terms of shape. Both great corals with great colour. Keep them anywhere you like, both these corals always look great.
