Bubble buckets pros needed!! new idea!!

Im building a multiple bubble bucket system and i had a brain fart. I seen alot of people on this site and other some other sites. trying to setup a multiple 5 gallon bucket circulating setup. I seen a guy try pumps but the pumps were to fast and would overflow the 1st bucket in the system. I seen other reservior systems use float valves and a ton of tubing. I thought there got to be a easy way. im building a 10 bucket system. bottoms of buckets will be connected so they will all self level with the 55 gallon reservior. I want to get the nutes moving to stablize ph and nutes and temp. so this idea hit me. years ago i had a freind that breed african fish. he made incubators for the fish with pvc. what i noticed with the inubators is you can move water with air. by puting a air stone within a pvc pipe. the air will push water.. so i been thinking of a way to make this work. the movement would be very slow but it will move. thats ok because this will let the buckets equalize. I think that the best way is working witht the last bucket in the system. with a pipe running back the the res. The res must be level witht the buckets because to high overflow. to low the buckets will drain.. so im asking for some ideas on making this work.. anyone?

After thinking about it all day i decided to just experement with very small pumps. should work as long as the whole system is level. im going to try it with the return line. just need it to circulate. dont need a toilet flush.. my idea with air might work but its way over my head.
and i just wanted to thank all the ppl of this fourm, after months of reading im on my way to growin fat nugs. ahh but who give a S@#T im just talkin to myself anyway.
