Bait tank question

I have a 17 Gallon Grayline bait tank and it has developed a problem with the aerator. It no longer sprays water out. The pump is pumping water and it pours out slowly through the hole in the front of the box where the pump is. Has anyone ever had this issue before and what did you do to resolve it?

Thanks in advance.

I have not had that problem but i would start by replacing the pump. It sounds like maybe the pump is weak

That's what I'm doing first. I found some fishing line wound around the pump shaft. Took it off but still doesn't pump. Found out that best place to buy parts was from the Tackle Box at Pottsboro as that's who acquired Grayline.

Check for trash, scales or anything clogging the pump
