The bulb in my 20-gallon just went out, I have had this one for almost 15 years. I went to my local Home Depot and bought the Plant and Aquarium bulb, got home and hooked it up and was totally blown away by the color change. The tank, fish, gravel everything now has a yellow tint to it. On the package it said it has a unique spectral and color range but I was not expecting this. I am going to return the bulb and possibly buy another one from there, any recommendations. I will also be ordering supplies soon and would take any suggestions for a replacement.
