I'm somewhat new to the aquarium scene. My daughter won a goldfish at a carnival so we bought her a small tank for it. Since then we've moved up to a larger tank.
We've had this larger tank for a few months now with no major issues until last month. But lately the pump has been sputtering.
It has a submerged pump and the section the pump sits in has become dry. I add water to this area but all it does is empty all the water back out into the main tank area. It never did this before and I'm at a loss for what is causing it.
Vie removed the filters and cleaned them but honestly, they didn't look dirty at all.
Any help would be appreciated.
