We acquired a new to us 300g peninsula tank with a Bubble King 250 Supermarin skimmer. I just don't think it's acting correctly, but the manual and videos I can find aren't the most helpful. Does anyone have one and would be willing to share a video of it working properly? I seem to be having a LOT of bubble coming out the bottom OR a ton of water coming out the top. It's used, so I was thinking any break-in period from manufacturing oils should be over. I must not have it adjusted properly or too low/high in the water column. Not sure and completely unfamiliar with this piece of equipment.
