I purchased a Tunze 9001 skimmer and it’s been running for about a week and I’m having no luck decreasing micro bubbles and cup overflows every few minutes. I’ve tried looking it up and there’s so many different opinions out there I don’t know who to listen to. I have it set to recommended water line and it’s in a chamber that doesn’t fluctuate. I have the air line completely open. It’s in the surface skim configuration. I want to know how other people had best luck breaking it in if that be at a different water level or air intake not fully open. Maybe it’s not breaking in because I have a pretty bare system as I’m awaiting an order of live rock so there’s really only live sand and some ghost feeding to add to nutrient levels. Thank you.
