• Approximate surface coverage is 24x24 inches (60x60cm).

Does this refer to water volume in the tank only and if talking about just tank size, for a 90 gallon should I go for three? Really like what I see and seriously considering switching over from MH to LED now.

If you are talking about the 3W Cree LEDs that are everywhere now a handy way to work it out is your tank LxHxW (all in inches) divided by 324. That will give you the number of individual LEDs recommended. Although that fixture has red and green LEDs in there too which are not factored into that formula. Their usefulness is still to be determined.

um.. thats a handy way to figure out how many gallons your tank is now how many LEDs you need. LEDs are based on coverage only so how many would you need to evenly cover a surface area not a volume.
