I am currently switching back and fourth between 14 and 20 bulbs simply for looks.
I run the 20's for a while and my corals begin to loose pigment then I go back to the 14's and the pigment comes back
I use to have XM10K and absoulty LOVED the growth but not fond of the overall color.
I have decided to go back to the XM10's for growth and Pigment.
As well as supplement with Actinic VHO for overall color.
Just to clarify when I say color I mean the overall look of the tank. When I say pigment I mean the corals actual coloration.
So to begin I have spend the last month researching bulb/ballast combos for actinic supelmentation. Let me save you the time trouble. The general consensus is that VHO actinics are considered to be the best. While you may not get the PAR from them like you would with T5HO's the overal apperence cannot be beat. It's actinic anyway who cares about PAR?
Today I orders an Icecap 660 and 2 VHO actinics.
The Icecap was a no brainer but I struggeled for a week over bulb brand and spectrum. I chose UVL (1)Super Actinic and (1)Actinic 454. The Super actinic peaks around 420nm and the 454 peaks at, yep you guessed it 454nm.
There really are not many choices when it comes to vho actinics. UVL is a very reputable company and their VHO's have been in the reefing industry for many years and are widly accepted as the "best" VHO avaliable today.
They are also the first to introduce a 454 VHO bulb.
I will play with this combo trying one of each at first and down the road trying 2 supers then 2 454's. I will also over the next 12 months try a few different manufactures and spectrums.
So here is where I'm at, I have the VHO actinic comming in tomorrow. and plan to get them wired by the weekend. I think I'll keep the 14K's in for now since they are fairly new and I don't want to spend the $$ for the XM just yet.
Tonnight I will post a few baseline pics with both the 14K and 10K bulbs.
Then more pics when I get the actinics installed.
