Aquarium Advice Regular
Just recently started getting a lot of microbubbles in my tank. I originally thought it may be the skimmer but its not. I ran the tank skimmerless for a while and I am still getting them. I guess it could be my return line. My return output is only about 2 inches under the waterline and sometimes I can see a whirlpool effect right above it. Could this be causing the problem?
