Rob,
Sorry about the tank... a lot of lessons learned for all of us. Here's to a quick recovery...
The lighting shows have been excellent, especially the
MH discussion. Makes a lot more sense now.
I was wondering if you could discuss the difference (if any) between the 420nm
Actinic and the 460nm blue bulbs. I use 2 65W
PC actinic lights to supplement 2 250w
MH on a 90 gallon SPS tank. I'm about due to replace bulbs and I was curious if there was a major difference between the two options. Both seem to work similarly with the 460nm bulb being a little brighter.
Just a thought.
Thanks
