My fish tank pump is loud and making bubbles. Is my fish safe?

The impeller, the part that moves the water, may be bad or there may be a clog or debris in the pump. If you can get to it, check it for wear or damage and replace it or clear any debris or blockages. If you can't get to it, you may need to replace the entire unit.
