This is the year that It's time for me to change my florescent lighting tubes.
I run grow lux for aquariums and plants in them to aid in the fight to maintain color. Some bulbs claim a 5-7 year life but I always feel better changing every coupla years.

I remember when I first moved my koi inside how the color fell and how it became apparent the following year I needed to do something.

If it was a perfect world, I'd remove the roof on my indoor facility and replace with clear plastic panels. here in the pacific northwest we get such grey days for the next 4 months that I think even the koi get depressed.

I bring the topic up in case we have some koi keepers with fish inside in the winter and no special effort to get them a full spectrum light. I was into a specialty store for hyroponics the other day to see what was new but that light is so bright, I'd think it'd blind the koi! Sure was hard on my eyes.

anyone else want to share what they do with their indoor facility?
