Hey guys, I'm debating on if i should use a double or single air diffuser for my 5 gallon buckets. I got a 35 watt pump running 4 5 gal buckets. I don't want the single diffuser to slow down air output, but i don't think it will much. I would think it would just cause that diffuser to produce twice as much air than a double would. Anyone have any experience with this?
