What to do with 14g

is it just on a plain table or dresser? there might be a piece of furniture you could get on craigslist. or build a stand yourself. you could probably do so for under $30. if ou don't want to do the extra labor, you could always go with your 2 pump plan. but you'd most likely need to drill for that also.

 

I have a drill, and its just on a dresser.

 

Don't use two pumps from one tank to the other and back .. that is a disaster waiting to happen when one pump fails..

Google "Water Bridge" have used it in the past to link 3 tanks in a row. Bridge 1-2-3 then pump connects 3-1.. Water level will stay equal and flow 1-2-3 through bridges and repeat based on the pump 3-1..

Bah here's a link in case google spits back that concrete stuff over a river lol..
Bio-Elite Aquarium Water-Bridge

Just have to be able to adjust tank heights so that the desired water heights are equal..

 

..wow. I'm def looking into that.

 

It's actually pretty fun to watch when setup properly ..

I used clear 4" tubes between tanks for the bridges.. Fish could swim back and forth between which ever tank they liked. All 3 tanks had a different 'biotope" style.

 

I used to have an ant farm like that. 5 different units, connected by tubes. That's really interesting.

 

Thats interesting!!

 

yeah i agree that is pretty interesting
