This is my first aquarium with sump. So I really don't have any idea with plumbing. It's a 60×30×21 peninsula tank (sump 40×25×25 stand.60×30×30). The tank is still in making process so I can still make some changes. Right now they give a design with beam animal drain (3 × 1 inch) and two 3/4 return with manifold ( I want to run a 55w lifeguard uv sterilizer and a carbon reactor through the manifold). will a single cor20 is powerful enough to run all the stuff ? Is the 3/4 return suitable for this tank? Any suggestion is welcome. Thanks in advance
