I just saw that the hinges of the sump cabinet are very rusted (metal rust flakes falling apart). The hinges are not positioned in a way that the flakes would fall into the sump, but I can see perhaps small metal dust particles can get in there. Even my hands and tools can have touched the rust and contaminated the tank.

Do you think that could be the source? I'm going to replace them right now.
