I currently own a Nuvo 8 gallon tank and am planning to get a Lagoon 25 in future. Which light would you guys recommend? Looking at the PAR comparisons on AquaIllumination's website, the Prime seems to beat the Kessil. http://www.aquaillumination.com/science/par.html I'd also like to know the PAR reading that members have measured with these lights. I've used a Kessil before (which died last week) and I was pleased with it but I am tempted with the flexibility of the Prime. Suggestions please!
