I am in the planning stages of a high light/high tech 75 gallon tank. I am slowly gathering equipment, so far I have the tank, versatops, 5lb co2 tank and Azoo regulator. I also have a 36" Finnex Ray2 which I am guessing will not be enough light for the 48" long and 21" deep tank. I also have 2 24" Marineland Double Bright LED lights. If I use all three lights on the tank, do you guys think this will be enough light for all the co2 I plan on diffusing? I also like the Current USA Satellite Freshwater LED Plus lights. Would a 48" one of these be sufficient? Would using the LED Plus in addition to my 36" Ray2 be overkill? Thanks and I apologize if this is too vague a request.
