- coral extension
- flouriscence under moon lighting
- growth, now you can't expect much in 3 days, but I can see some white ends on some corals that were not there 3 days ago (an indication of new skeleton growth)
So I would say having 3 would be fine... I did like the 14K look, but with research I found that most corals are within the first 5 meters, and the Ushio 10K bulb replicates this region... Therefore I decided to switch back and can say that it does look really nice and I actually like it better than before.
I also run the ushio 10k on my frag tank and love it. Its not yellow but more white. My Colors never look better than they do after being under the 10k.
