VHO Red Sun 34"

I was hoping this bulb being advertised as Red Sun would be like a bloom red bulb 3000K. This bulb is literally RED! I'm not sure what this bulb is designed for. It will make your tank look artificially all red color. Your fish will look red your plants will look red your gravel will look red. The water will look red! Its all red!!! I purchase 4 of these as it would of costed me the same if I purchased 3 as you get free shipping at 4. shipping comes out to the same price as another bulb so made sense to buy 4. It was a big waste of money. I think this bulb could be used for decorative purposes if you happen to need a red flourscent light. these bulbs are for sale cheap!
