Please dont misunderstand but that is a bad idea.
You really dont want to be sharing water between tanks. I dont even share things like nets and siphon hoses between tanks the risk of killing all your fish or introducing some parasite that spreads to other fish is extremely likely.
I once made the mistake of sharing a net between tanks and ended up with 3 tanks with an ICH outbreak.

I'm with Nick.....unless it's for a sump it's best to keep separate tanks separate.
This is not quite the same thing, by a lot. When you transfer water from tank to tank, you are also transferring everything in the water, from ammonia, pathogens, pheromones and allomones, to...whatever else. This is not at all good for any fish in those tanks.

I looked at the photo closer and realize those are bins, not tanks and since they are relatively small, one could make the case that a few connected small bins (or tanks) isn't much different than one larger bin or tank. DIY Joey has several 125g stacked tanks and each over/under pair share a single sump.
Still, the risk is higher and why bother? What really is gained by connecting the small bins together?

Connected or not, the 'required' water change frequency/volume is the same.
I don't understand this, could you explain this for us? I'm not sure any of us are grasping it.
The only way to have a flow of fresh water through an aquarium is to have it somehow connected directly to the faucet. Running water from one tank into another is not fresh, assuming (as I think you said) there are fish in both tanks. That is the same as having all the fish together. The only way to keep fish healthy in small tanks is to do major water changes with real fresh water. Discus breeders for example often do one, two or even three 90% water changes in fry tanks every day. But that is using fresh tap water, not water from another tank with fish.

But merely connecting tanks as you described does not change polluted water with fresh water but just circulates dirty water around. Am I not understanding something?
