while I'm waiting for my 300 gallon tank to be made, I have been doing some preliminary plumbing..I have a utility closet 2' to the right of where my tank is going. I will be hard plumbing this tank and am planning on (1) echotech L1, located in the sump, feeding the equipment in the utility closet then going back to the tank to (2) inputs. Then (1) echotech M1, located in the sump, feeding a small frag tank under the tank then to the (2) other tank inputs. The chiller, which is plumbed online from the UV sterilzer, will have a separate pipe going back to the sump. I have never did a design like this and was wondering if this setup will work.
