What size sump do you have? I have made a mistake. I have an aga stand and put a 20gal sump in it when I set it up. It put the sump in from the top. But know the tank is on it I can’t get the sump out. I wanted to set up 2 10 gall tank vertically with the tank (they would stick out the back)for a refugeum how should I get the sump out and also what size sumps do you have in your 72 tanks???
