2 Small Tanks, 2 U Tubes for water movement

So I'm looking to set up a tank at work. Unfortunately due to restrictions, I can't really use any electricity. Someone mentioned that if I use two U tubes one drawing water from one and the other drawing water from the other, that this would create water movement without electricity. The only other thing to consider is temp. I wanted to look at temperate species that could handle room temp water (pretty consistent around 70 here). I was thinking about the Catalina Goby, but don't really want 2 Catalina Gobies. I also thought about dwarf seahorses, but I understand that they are a tropical species? For some reason I thought that most seahorses prefer colder water, but I guess they are the exception? If I did the seahorses, I could actually use the second tank as a pod population builder and just fill it with rock and macro algae. Then the only thing I'd have to do would be to protect the seahorses from getting sucked into the other tank, maybe a small sponge filter on the U tube? Would typical office fluorescent lights work for growing most macro algaes? They'd be on the ceiling above the tank of course. Just looking for some ideas and direction on this idea. Thanks!
