Greetings, I'm just starting a 20 gallon reef tank. I bought a used setup from the lfs and it came with the basic T8 hood which I'm looking to get replaced belt the end of the month. One employee of the lfs has Radion and loves it but I can't quite justify to myself to put that expensive of a light on a 20g tank. The other guy has AI Hydra and he says while it's not quite as nice as the Radion, it gets the job done. Then there's the Current USA Orbit Marine Pro. Which I've also been reading about. Does anyone have any opinions on these 3 lights? Why did you pick that light?
