Hi mate,
awesome tank. are the bulbs over driven? You only have 1 white bulb in your config. is that the same config youve always used? your coral growth is amazing but you have lots of blue light. I though you would need more white but you certainly showed me otherwise.
Yes, they are overdriven. I can't say if i would use different with regular driven bulbs, as I have not used them, but on my setup the daylight bulbs were just not my cup of tea. Just to strong. Not as much when it comes to bleaching (though I have seen this IME), but rather having a bulb combo that pleases the eye. Without more bulbs, even one GE 3k could not be compensated for with almost all my other 5 bulbs... The 6k was only slightly better.. This was why I started going a different direction and used the red "colored" bulbs.
The fiji purple and procolor bulbs are far from blue, or high kelvin bulbs IMO.
Though there seems to be little info on their actual kelvin rating, I consider them to be on the red end of the spectrum, not blue. Especially the procolor, it is basically pink... The fiji is like a aquablue (same PAR) with some red and purple, it really is unique.. They really pop certain colors, and shift the blue plus bulbs back to white in a way that is not overpowering like the daylight bulbs, which I find make everything washed out and dull..
When all the lights are on it is very much "white". In fact, far more than when I ran a large portion of aquablues, aquasuns, or even GE's. With daylights and blue plus bulbs (and a SA) that i see sommonly recommended, it just looked yellow with blue shadows to me.. very dull... Overall it looked "white" but nothing really popped..
It is not just the color cast by the lights that I found important, but the colors popped that make a tank look "white" to me...
This combo really pops everything and is balanced IMO... I have used them all.... seriously though, every bulb out there..
JMO... I have found that growth did not slow either, so I am set on this combo.
