I have been battling Aptasia for over a year and was about ready to nuke the tank. After seeing this today, I think I have the perfect tank to test this theory on.
Edit; I lied, this tank only has an 8' run stright up from basement so skimmer might work.
I'll have to see about getting one of these or maybe remove the baffle between sump chambers and see if I can get skimmer bubbles up in my tank. Might be a stretch for that since its a 20' run from fish room to display..You need the wooden air diffuser. You get finer bubbles than stone and more of them.
