Medium light for a 46 gallon bow front
Does anyone have any suggestions on how to achieve medium light on a 46 gallon bow front? The tank is 36" long and about 21" deep. I currently only have a 36" Coralife T5NO on it. I'd prefer to stay with a fixture that rested flat on the tank hood.
Would adding another of the same fixture work? That seems like it would be the cheapest route if so. I wouldn't mind buying another fixture altogether as long as it didn't get too expensive and could sit flat on the tank.
Let me know if you have any ideas, thanks
