Well it has lasted many more years than most, But it finally let go around 12:30am with a crack from the corner overflow drain hole to the front of the tank. Being a bottom glass crack there was no stopping or slowing it down. Thank goodness I was home, and had the 100gal sump and refugium tank going. Moved all the corals, fish and live stock down there. But now what. Who in there right mind would replace it with another tank with such a high failure rate. And who has the money for a custom tank. Im now at a loss. Do I replace the bottom glass, reseal the whole tank, and drill the back for a real overflow..... Anyway, im now stuck to the web looking for solutions.....
