Current Lighting setting question

Susan Edwards · Apr 4, 2018

I have the current ic marine pro, 72 inchs and love the programing and the loop system. Right now they are on brackets 7 inches above and I'll be dropping them down to either the 5 or the 3 inch levels. As it is a bit of a pain, might go all the way down and lower intensity for a while

I've got them set at
blue 100
white 40
green and red 50-55

Question: is it better for corals to have more white or less? Is it mainly just what you like the looks of? That the corals will get what they need from the other colors, mainly the blues?

Is my setting good for corals (micros, duncan, torch, monti's, some sps high up)

One of my concerns stems from the tenius acro I put in the tank. Removed it from my 66 as it isn't getting any PE. In the frag tank, same yet a tenius I just got is full of PE. Even in the new tank, it is still fully polyped. So I put the older one in. It was a blue tenius and in the new tank, it looks more brown. Frag tank it was still blue. So do I need light adjustment to get the blue back or is it more of the lighting appearances. Will ask this ? in the sps forum as well.

I´m not familiar with that fixture but according to your colour problem I have some thoughts. Have you try to take down the white to near zero and rise up the blues and RGB to max? If you get a too blue hue - just reduce the blue till you get the colours you want. You can also rise the white and see then the things turn brown again. It can be that way that 100 % of the blue channel and 100 % at the RGB channel has not the intensity you need for a good growth but if that the case - you can rise the white during hours you do not look at the tank. I run my tank without white (phosphorus coated) LEDs and I get the colours I want.

I haven't tried rising the green and red to 100% as I'm afraid I'll get algae issues. Blue is as high as it will go. Only that one coral turned brown. Rest seem pretty happy except maybe one micro down at the bottom. Will experiement with some of the colors and see what I get.

Told my hubby I wanted him to help me lower the lights and he thinks I don't want to do that--got all technical about light bouncing off sides, coming from a gardener's viewpoint but with led's, from what I've read and others have said, lowering the lights will up the par near the bottom etc.

so far, lighting seems to be the most difficult in going from an aio to this new tank
