My personal opinon is to stay with VHO
. I have both VHO
. I first had PC
and loved them and then got the VHO
. Both used the same specitrum 2 X 10K and 2 X Actinic. I like the color apperance of the VHO
better. I also replace my PC
bulbs every 9 months. There is a noticable color shift after 9 months to where I feel my corals are at a disadvantage if I left the bulbs for another 3 months before I replaced them.
I am currently at 10 months with my VHO
bulbs and I dont plan on swapping them out for another two months.
