T5's
T5's
hi,
I am using four (2 aquablue, 1 pure actinic, 1 6000 K mid day) 39 watt T5's on my 30 gallon reef tank. Growth rates have been good to excellent and I have only lost 1 acro to RTN (The great sliming Incident of 2006). Coloration is good with no bleaching and the only disappointment that I have experienced is that my blue tort is more of a brown tort with blue highlights. It was a spectacular blue green with metallic purple and blue highlights at the store. I probably could go with another aquablue bulb rather than the daylight to bring out the blue, but I prefer the balanced light of my current setup for photography. In my tank, its feeding tentacles are always out while they were retracted at the store. I am running these bulbs with the standard Tek light ballasts. I have read that you can increase the light output by using an Ice Cap 660 ballast. I would like to see some data on this observation before upgrading the ballast.
As Always,
Jim Z.
