I inherited a 4-MDQX-SC that had been run on a reef system for a decade. It had never been cleaned, nor had it even been oiled (owner had no idea), but it still runs reliably without a hiccup. It's gained a bit of a cyclic hum in its old age, but I am pleasantly surprised by the amount of neglect this thing took without complaint.
