The difference is the amount of light put out and ability to penetrate the water. NO
is dull and drab looking. PCs will make your tank POP! The difference is amazing. If I had it to do all over again I would have bought a PC
retro kit so that I could put that in my canopy and then my upgrade path would be easier when the inevitable (needing MH
lighting) happened. So now I've moved the PC
fixture onto my 65g and put the MH
into my hood. I'll be adding that PC
retro to it to add a bit of actinic for the early morning/late evening light cycles.
