Since yesterday night my return pump has started giving off a light electrical current. when i stick my hand in it, it is barley noticeable, but it is noticeable. I have all lps and soft corals, along with several large tangs and some smaller reef fish. I am going to get a new pump, but it probably wont be for atleast afew days. How unhealthy is this for the tank, the fish seem like it doesnt bother them, act normal and were eating. how detrimental is this to the fish and coral and has anyone expereinced this before?
