My GSP is not as neon green as it used to be...what causes this and what can i do to bring it back to its original neon....ness.
How old are your lights as they age there output can change and has any thing changed in your tank over the time that they changed color.
i no longer have a protein skimmer but that is about to change. I converted from a 14k to 20k bulb also. I am going back to the 14k when this bulb gets near its end.
Was the change in bulbs before or after the GSP color change? because that might be it, coloring of the bulb wise and age wise
