Manifold Design for 300 Gallon Aquarium

[MichaelsReef]

I am in the process of upgrading my 180 to a 300 gallon. I am planning the plumbing process as I wait 8-10 weeks for my tank to arrive. Can anyone tell me if this Manifold design will work. (1) Echotech L1 will be plumbed from my sump to my utility closet 3 feet to the right of my tank...then T'd off to the manifold before going to 2 tank inputs..The Chiller will be plumbed back to the sump. Then (1) M1 pump will be plumbed from my sump to the 2 other tank inputs...with a

gate valve feeding my small frag tank under the stand.

I got my first shipments from Bulk Reef Supply. But since, I have found an online vendor who is half the price. Pvcfittingsonline.com.
