connecting tanks

I want to connect a couple of tanks together but I don't think its feasible. is thew idea to run same tanks off on large sump? I don't have a basement or a place I would want to put one so to run separate sumps for each tank then somehow connect tanks would this still be an option or not worth doing?
 
Like a lot of possible projects, the correct answer is, it depends.

Putting multiple tanks into a single system has advantages and disadvantages. The main advantages are a larger volume of water, all the water is the system is more or less the same, and you only have one system to deal with. The disadvantages are you can't maintain different water conditions, and if you have a disease problem it's in the whole system, and if the system fails you loose everything.

So you need to consider what you are trying to accomplish by building a common system.

It could work out very well where you want to have the livestock in one tank protected from the livestock in another. For example, if you wanted that parrot fish, but didn't want him munching on your SPS corals. It could also work out well where you wanted several smaller tanks connected. The smaller tanks might not justify large powerful skimmers, or reactors, but as a combined system, the costs would be manageable, and the water quality would be a lot higher.

If the tanks are in close proximity, you can use one pump/sump to feed both tanks. Both tanks would then overflow back to the common sump. It is considered a reeeaallly bad idea to try to feed one tank and then use a pump from that tank to feed another.

But lots of folks use one pump in a sump to feed two (or more) tanks.
 
my tanks are combined. one main pump. one skimmer. one chiller...

Besides the excellent info DaveK gave I'd want to ask the obvious question.

How far apart are the tanks from each other?

Generally speaking if you aren't doing a basement type setup OR if the tanks aren't very close to each other it's probably not going to be worth it.

tanks are right next to each other the 55 gal. to the right I was thinking of putting a 30 gal. cube for seahorses and connect that with the 150 in the middle.
The thing is my sump is only one of those pro 200 wet dry w/o bioballs and pretty much takes up the entire space under the 150. with external pump. I'm feeling like I'd have to go with a larger sump. then a larger protein skimmer. the cube is not RR. either is the 55. I don't like the idea of those skimmer boxes but I might just be paranoid.

Seahorses optimally need a separate system from as they need MUCH colder temps than we run our reefs at. As far as proximity, those tanks look to be a fine distance from one another, so technically very feasible.
