Hi, all.
I'm confused about how to choose proper lighting for my freshwater NPTs.
I have one 20L tank that I bought a 30" T5 HO fixture for. The lamps were 24" and 24W. I thought, since this translated into a bit more than 2 watts per gallon, that I would be fine--but it was clearly far too much light. The single T8 Sunlight bulb I got just does not light up the tank the same way, though.
Now I need to choose lighting for a 55-gallon freshwater NPT. How do I know the relationship between watts and K, and how do I choose the best light? While I would love to know a great fixture in specific, I also want to know how to choose a fixture myself, for future reference.
Thank you!
