So I've had this HOB
refugium and skimmer for a week and a half now and I don't think the water pump is pulling in enough air. There are very few bubbles rising from the pump when it is even working. If I shut it off and restart it, it frequently doesn't even pull in air. The air line fills with water to the level in the fuge. After 3 or 4 restarts it starts sucking in air again, but only a bit. I'm thinking I may have to rip the pump apart to see if there is a defect. Any ideas what I should look for?
For now I have an air pump blowing into the air line and it's actually working great. Got some ugly skimmate forming. But it is too loud and I'd like to get the water pump Venturi working like its supposed too.
Perhaps others have had issues with the odysea pumps?
