Quick noobie question

[gobbles]

I have two hoods on my tank, One with "sun glow" bulb and one with "aqua glow" bulb... I have googled but found little to no help. As far as my research told me the sunglow bulb produces heat to heat the water, but that is all the info I've found, can anyone help me figure out what the aqua glow bulb does?

Aqua-glow is for colour enhancing. Think it helps enhance fish colour.

I noticed when my frog sets at the end of the tank with the aqua glow light he looks a lot more orange, and when he sets at the sunglow end he looks more albino... but with the two diff lights I can tell they do have a color difference by the color of the rocks... one looks more like a florscent(sp) light

The Sun Glo bulb doesn't (or at least it shouldn't) be producing anymore heat than the Aqua Glo bulb or any other flourescent bulb for that matter.

Hagen produces various bulbs such as the Aqua Glo, Sun Glo, Life, Power Glo, Flora Glo and Marine Glo. They all have the same wattage per the same size bulb but they offer you different lighting spectrums depending on what you need. I've used the Aqua Glo, Power Glo, Life Glo and Marine Glo. The Aqua Glo is a standard bulb that produces a more white light and helps to promote colour in fish and plants, the Power Glo produces a more pinkish light that enhances the colour on most fish, the Life Glo bulb producs a more yellow light enhancing plant growth for planted tanks (I would assume Flora Glo is close to the same) and Marine Glo produces a intense blue light (actinic) to enhance colours and help the development of marine invertebrates.

As far as the "temperature" part goes, I think you are referring to the colour temperature that bulbs give off which has nothing to do with temperature that one would assosiate with being warm or cold. Colour temperature is based on the light specturm and goes from (red/[cold] - blue/[hot]) and is measured in degrees Kelvin. The reason why red is cold and blue is hot, think of a fire, a hot fire/flame is called "red hot" but an even hotter fire/flame is called "white hot" and a "blue fire/flame" would be even hotter. More or less, it's the amount and type of colour that the bulb produces and is visible to the eye.

Lighting is vary important to an aquarium. If you have many plants or a reef tank, it's very important to figure out what kind of lighting you need. What kind of tank do you have?

[gobbles]

Its a 125 gallon tank... I just planted some plants in it and they seem to be doing okay.

[A340]

Depending on the plants, they can require anywhere from 2 to 6 watts of lighting per gallon if you really want them to flourish. The way you have the lights set up, do you have 1 bulb on each side or are they located behind each other?

[gobbles]

they are next to each other, the guy i bought it off of said they grow better under the sun glo bulb so thats where i planted them...
