wet dry for a 15 gallon?

has it been done, and what models of wet dry's and pumps could be used without overpowering the tank?

 

It would add a far larger area or margin of error to the tank I like a wet dry myself great for adding more oxygen and releasing unwanted gases . A small sump and little container just filled with old cleaned plastic drink bottle caps or weed eater cord or even old fishing line will do fine , with a sort of drip plate will suffice for a wet dry. and all the water does not have to pass through the wet dry just a by pass will do of about 1/3 of the total turn over per hr. will do if flow is a concern ? I also have never had one turn to a nitrate factory LOL
