PCs good for actinics?

[ScubaSteve]

PCs are actually pretty good despite the bad rap they have. I actually use high power PCs in my research that are waaaay more powerful than most T5s (for the same size bulb). Just get a good PC bulb and you're set. I recommend the UVL bulbs from BRS. They're super strong. They actually made some if my SPS bleach when I made the switch (and I have even reduced the time in them!)
