Thanks.
It has a weird look right now with actincs. But easier to get a pic. I have an aro as220 running on both tanks with an actinic white and an actinic blue on each(only 4 ft each). The aro ballast in my main will go over to the 75 but for now it gives a funny look. I do like that the actinic white brings out the reds, but it also makes the blues redish. When I move the aro from my display over to the 75 and install the icecap I'll have 2 blues and 1 white (5 ft each) which will shift it a little more to my color preference. Plus, a lot more watts.
Also, my display tank actinics were set up temporarily so I just bolted the encaps to the canopy on the front and back so they actually point at the opposite side of the canopy vs. down into the tank due to the internal reflectors in the bulbs. Just the oreintation of the bulbs will make a difference in look.
I've noticed that it looks whiter and brighter in the 75 than in the 180 even though they have the same ballast and bulbs so I can only guess it's that my 180 is getting the actinic light from reflectedd down vs. pointed down and it changes the spectrum that makes it to the tank.
