I have a JNS VS-1 HOB protein skimmer and I have never witnessed so many micro-bubbles! I have been active in this hobby for many years and used to be a sales rep in the industry. Having said all that, does anybody have similar experience with this unit? It may be sold as Aquamaxx in other markets. Tried cutting air, etc. but no good. It's getting to the point where I may just remove it, the bubbles are so bad.
