I'm planning to use a Panorama Pro 12k White/blue and blue/magenta retrofit for my 15 gallon nano reef tank that's 15" tall. Can you recommend a good height placement for them? My current CFLs are about six inches off the surface of the water.
We usually recommend mounting our modules 3-6" above the aquarium/water level. Please remember, the Panorama Pro LED modules are IP65 rated and water resistant, but not designed to be exposed to water for a length of time. If mounting these modules over a nano-aquarium, be sure to mount them under the plastic lens of your existing hood.
