Finally to the plumbing stage of my 300 and this a schematic of what I’m thinking. I’ll be running 2x ecotech m2’s for return pumps. Both will have 1” plumbing till the bulkheads in the top (6 total bulkheads across the top of the tank,3 per pump) which they will then reduce down to 3/4” loclines. My main question is im going to be plumbing in a 3” 90w lifeguard Uv light. The red hash marks are where I’ll have ball valves. Does this look correct? Also planning to mount this behemoth uv filter on the wall behind my tank vertically since I can mount into a stud. Should I go with a ball valve that’s 1” or larger for the uv side?
