Hey all,
I've noticed that every now and again, my 220g needle wheel Super Skimmer surges. It'll blow big air bubbles out the return tube that's in my 46g. (using it in HOB mode right now until it goes into the 90's sump)
Seems like most times it won't do it, but every now and again, it seems to get on a kick and you hear this big "bluuubb, blub" and big air bubbles are coming out for a while. Not sure how or why. Especially when it happens I haven't changed any settings on it.
Any thoughts?
