I am setting up an acrylic 450 gallon with dual overflows this weekend. Previously had a 220 gallon that started leaking and so we figured we might as well go big or go home. The question I have is whether or not it would be reasonable to put a uv light into each of the overflows, which are covered and you cannot see in them. Would like to optimize the uv lighting to where it's killing as much as possible. I will be cycling for quite awhile, so just in the planning process right now. Not only for space or economical reasons, but I feel like a uv light in each of the overflows would do double-duty. Looking for any holes in my thought process here. I don't necessarily mind spending the money for an encapsulated one, just feels as though you'd get more use for it if it has more exposure to the water itself, and more at once. TIA for any help or guidance.
