Need help. I’m new to this. Does anyone own a SeaClear bow front freshwater System II aquarium? Instruction had no clear picture and after set up I have streak bubble lines around the tank. I read another thread that said to submerge the free end of the air tube thats attached to the filter motor. This hasn’t worked to clear the visible lines that appear to be bubbles? It’s an acrylic tank. I’m not sure what I’m doing wrong. The lines obstruct the view. It’s far from seeing “clear”. I only have a few days to get it right before our fish come. Help! I can’t find a customer service for this company?
