Updates:
Had to modify the shelf in the chiller compartment of the stand to allow it to fit. Circular saw made quick work of it. The way it came from the factory was not at all serviceable. CADE/Algae Barn tried to fix it by sending new plumbing, Adam from CADE thought the drain plumbing was not to spec based on the pictures I provided. This didn’t fix the issue unfortunately. Thanks to @Reefer911 for helping with troubleshooting, as he had the same issue with his tank.
Do you have pics of the shelf mod? I'm having the same issue with my Cade 1200P
