Wow, just Wow!!! Hey Ryan, this is Anthony from youtube. I'm planning out my system for the summer (fingers crossed) and seeing your build I'm sooooooooooooooooooooo hype for it. That tank is BONKERS!! Couple of questions for you. How tight a fit is the Synergy?? No issues getting the doors back on I'm assuming. When do you expect to put water into the system?? I LOVE the Varios pumps too man. I have a Varios 8 for my Reefer425 and a second one sitting in my garage for backup. Probably go with a Waveline for my 750XXL though as I want to go with a different color scheme.
