  • Description

It is recommended by lighting manufacturers that you replace your saltwater aquarium bulbs every 6 months.

Why is this important?  The blue spectrum called kelvin (also called K) is diminished after 6 months even in your Nano Cube.  Your corals and such need this blue spectrum to flourish.  You should see a improvement in your tank after replacements are made.
