Ordered a new, larger sump for my 125 gallon tank. The tank is 72 long x 18 wide so should have plenty of room for a Trigger 36 long sump. Or so I thought. Once the sump arrived I discovered the custom stand restricted placing the sump under the tank; lacked just 1 inch of space to maneuver the sump through the doors on the stand. But that one inch may as well have been 6 inches because the sump just would not go through the doors, even after removing them. BRS did take the sump back with a restocking fee and return freight, so I now have a 34 inch Trigger Sapphire sump on order. Sure hope this one fits!
