I have a 4x54w T5 fixture (individual reflectors).
It came with 2 actnics and 2 daylights at 10000k.
I accidentally replaced the 10000k that went out with a 28w one (wondered why the coral's growth slowed down!) and now the other 10000k bulb went out. This seems like an opportunity to upgrade my setup - my priorities are:
1. Health of corals, fish, inverts (I have a frogspawn and some zoos).
2. Appearance
I've read conflicting views on whether 10000k is the best for corals or if I shold put in one 18000k or find a 6500k daylight (I thought 6500k was actnic only? I guess I don't know as much about lighting as I thought I did...).
Basically, what is my ideal setup for the 4 bulbs to make my corals happy?
