Hello fellow RIU. I'm looking for opinions on which waterfall displacement is best. Currently building a 2 tote RDWC with a controller and water reservoir. I have to some videos hoping you can help me decide on the choices. With one of these methods, do I need an air pump to supplement as well? Would it increase my yields with air pump?
