Hi guys sorry for all the beginner questions. I have been researching a lot of DWC and RDWC lately and I see that a lot of people have a recirculating system inspired from Heath Robinson. I also see that Double D gets very good yields from a recirculating system, but he also seems to use air stones. Does Heath use air stones as well. Is there a benefit to using one and not the other to create DO or should I use both for maximum DO?
