The HQI's are 14,000k Phoenix bulbs, which to my understanding are a bit bluer than most 14,000k's.
That said, I am going to be changing them here in the next month as they are about 2 years old and my tank is starting to grow some serious hair and red slime algae.
I am probably going to give the new Iris 14,000k bulb's a try, they are suppose to be comparable to the Phoenix bulb's and only cost about $24/each.
I do use the PC
's to simulate dawn and dusk, they come on 1 hour before HQI's and turn off 1 hour after the HQI's. However they are also on the entire time the HQI's are on.
I was just curious if the 50/50 may offer more (for lack of a better word) light for the corals.
Obviously spectrum matters for coral's, so I know that 96w is 96w, but rather than the Actinic spectrum it would be a daylight spectrum.
Hopefully that makes since?
