Hey guys, It says these bulbs, are good for increasing color of fish, AND good for corals and inverts, it states on it, that it has an 18k output.. how good is this actually, and as far as corals go, what could do good under this lighting? Since its mostly a FOWLR tank, i will not upgrade lighting more then this, BUT if i can have SOME soft corals, that would be nice too.
"PowerGlow" Bulbs?

never heard of a bulb with an 18000 kelvin rating before. but since 20k bulbs colour up coral nicely, and 10k gives you good growth, i'd imagine 18 would be okayish for coral, maybe supplemented with a "daylight" tube.
As far as i was aware, the powerglo are a FW planted tank bulb???? maybe wrong on that and they have dual usage, just never heard of a marine system using powerglo bulbs....
The box says,
Power~Glo Fluorescent Aquarium Bulb
- 30 W
- 36" (91 cm)
- 32.5 mm Diameter
- Service Life - 9000 hours
- Promotes coral, invertebrate and plant growth
- High intensity
- Photosynthetic deep marine spectrum
- Total illumination for living corals, marine algae and freshwater plants
Does its say on the box, exactly what wavelength (nm) these emit on??? That pic above simply illustrates the different colours which emit through a given wavelength and not the wavelength of the the perticular bulb..
As a side note, zooxanthellae best uses 420 - 490nm range (blue hue), so, this is what "most" marine lighting systems are designed around...

ok this is what i know
hagen put 18000k as good for plants yet it isnt
it is a general bulb for fish
so as a basic
lifeglo is for planted tan ks and s/a setups
powerglo is a general bulb verywhite good for african cichlids fowlr etc.
marineglo is a 24k(maybe less) bulb that is for corals.
also doesnt that picture say on the bottom thsat the blue is on the 400-480 nm part f the wavelength?
