No I don't know anyone doing a dual, I am going to try once I get a sump going. Like I said if you size them to be the same surface area as 1 large one there is no difference and they are not competing with eachother so long as the total surface area of the 2 is the same as the 1. For example 1 that is 5x5 has the same surface area as 2 that are 2.5x5 or perhaps 1 3x5 the other 2x5. If you over sized them to have a larger total surface area then yes it could lead to them battling between them but even then you can use it to an advantage when it comes to cleaning. Clean the more heavily covered one and that would allow the other one to to pic up the slack then clean that one. You would reduce the risks of small increases in the nutrients in the water. The reason I would do 2 is for the cleaning, clean one one week then the other the following it's the same principle as cleaning one side of a big one without the risk of loosing the algae on the other side. Another benefit of doing 2 would be if there is limited space then you could place one on either side of a reactor or baffle or whatever else might be in the way.
