when you get closeto the tank, tthe water doesent look cloudy. pinkish colord tubes? the bulbs arnt pink, when you look at them next to each other, the 10 k looks blue, more like the blue on a pen, and the 67k looks slightly yellow, but only slightly. when the light are off, the bulbs look white, like ordinary flourecents that you see in a house.

I have a theory. I believe that the pink tube is causing an interference pattern with the 10,000K tube, thus creating more blue wavelength. This makes sense.

Light, which can behave like a particle or a wave, will do this. You see it frequently with, say, multiple bulbs in a chandelier or even with street lights; You have a row of streetlights all gleaming white, but one starts to go out and become more yellow over time. The point when the crisp light white beams from the working street lights and the old yellowish ones intersects makes for an area of hazy bluish, gray or reddish gray which isn't so easy to see. The same thing happens with that chandelier: One or a couple of bulbs go dim, or the wrong bulb is thrown in and the light doesn't look quite right and creates these off hues unless you have enough bulbs to wash it out.

If it won't break the budget, remove that pink bulb and put in a white, 6700K bulb and I'll bet the problem resolves itself.

is the 10K baulbs the pink ones then? so in other words, i sould just replace the two 10K baulbs, or all my baulbs at once, with 67K?

Whichever ones are the pink ones, I'd replace with 6700K bulbs.

Sorry, I got a little lost for a second.

Additionally, I thought of mentioning this, after the fact though it is. Pink (rather reddish) is on a larger wavelength closer to heating lamps and radio waves. Blue is a very small wavelength, closer to ultraviolet and microwaves. Since pink is an already attenuated because it is reddish, then the water would absorb it in short order leaving mostly blue, even at the shallow depths of a typical aquarium. This is my reasoning.

If I remember the specs right for your rig, the pink one is supposed to be the 6700 bulb and the white one is 10000.

10K bulbs are white,6k-67k bulbs are yellow/greenish. The pink bulbs are either aquamedic planta bulbs or something similar. I use one red T5 bulb in most of my fixtures to bring out color in fish and low nitrate plants.
