Fluorescent lighting: Which bulb is
I have a 55gal with 2 40watt 4foot bulbs. Both have Coralifes
10,000K. I know that I will probably need more bulbs to achieve maximum
plant growth, but for the time being, curious to know which bulb has
the best results for both fish appearance and plant growth. Its
just to confusing reading all of the manufactures claims Ideal
for freshwater plants, maximum plant growth and so on. Im
looking for PERSONAL experiences. Thanks.
- Whew boy Chris,,this a a can o worms topic..lotsa opinions...just
remember this is a very personal topic..a what looks good to you kinda
thing...blue and red will get the photo thing going and green too...blue
can get algae going on the higher plants and red the other way...You
do need to get at least some sort of full spectrum light in there...I
like a combo of coralife trichromatic and GE chroma 50...or Phen Plax-tri
lux...again personal choice..but as you said earlier a bit more light
might be in order...you are barely running 2 watts a gal. now.
- I personally LOOOOVE the sylvannia luxline 6k day bulb. It's inexpensive
and I successfully grow many, many plants under this light bulb. I
order it at Petwherehouse but it doesn't seem to be present on their
online catalog. It's listed in their magazine catolog though. Personally,
I prefer color temperatures within 6000-8000K because they're closest
to natural daylight (I think its 5500 or 6000) because I think that
they make the fish/plants look more natural. Fish/plant colors look
decent if not fantastic under those temperatures too.
- When Jeff said can o worms, that's exactly what I was thinking:)
Anyway, it really does depend on what you are growing and using it
for, and what you want it to look like. Some people like to light
reefs etc with the higher K bulbs like 10,000, with additional actinic
etc to get that "bluish" appearance that you see when you
are snorkeling or something...i currently run a compact fluorescent
system with 50/50 10K and actinic and my plants are growing quite
well...i would say the limiting factor is co2, but anyway...it does
have somewhat of a bluish tinge, and I am planning on replacing with
a 5500K bulb or as close to that as I can get. As lboy said, it is
closest to natural spectrum, and looks by far the most natural.
