NO Lighting and Coralline
 

Anyone out there running NO fluorescents and getting decent or good coralline grow out of them?

Many moons ago I did and the coralline growth was great. I would say even better under lower lighting or more actinic type lighting, which is still lower par.

I have 2 power glos on a 20 gal that actually produces the best growth out of my three tanks.

Great to hear! I want to make some grow-out tanks for live rock and this will save a ton on costs if it works.

What color bulbs? I was thinking of half 10K and half actinic, is that what you were using?

N.o.
 

I have always used NO for actinics. I have (2) 48" 40 watt actinics over my 90 supplementing (2) 40W 48" 10000K and 14K 250W MH. My coraline growth has always been exceptional, and you can use the actinics for a long time. (mine are over a year old and still have good life left in them. I'm sure that others will disagree, but the results speak for themselves.

T5 bulbs are reasonably priced, compact, and efficient as well, so I might retrofit with them in the near future.

Hope that answers your question.

Rich.
