I have a empty 72 gallon rimless aquarium that is drilled. The water flows over an overflow box, down to a sump where its filtered and then pumped back to the top tank at almost 600gph at the nozzle. Could i set it up as a type of rdwc? Plant 3 or 4 plants and grow? It already has light hangers, top off reservoir. And excellent circulation. No mechanical filtration is involved.
