I need help. I just put my glass hydrometer in my sump and the 1 1/2" bulkhead that is attached to my pump sucked it in. The pump made a wierd clicking noise, so I unplugged it. I detached the pump and found the hydrometer with the end broken. The red temperature fluid line was not broken. but some of the little (lead?) balls are missing. The tank ran for about twenty seconds. Do I need to worry?? The tank has nothing but sand and salt water in it. I just set it up. Thank for helping!!!!
