Trying to learn more aout the gas exchange. Any tips/comments?
IMO...gas exchange is not your problem...I have the powerhead moving 2/3 of the surface water pretty well. I am going to get a smaller powerhead for the opposite side. This side gets the scum at the top.
I dont have a skimmer. I noticed the frozen brine shrimp I throw in causes a lot of the scum. The two power heads would eliminate the scum i assume.
