Koiguy, I have a 100 gal stock tank and a sequence 4200 pump. I was wondering if you can make a weir for my tank with high sides. I want to also run a multi level waterfalls using a single Tee running from the tank into pvc pipe at different heights to create multiple waterfall points. I am not sure how much room I have on side of tank maybe I can go wider than 13" or maybe suggest something better that makes more sense. Attached is pic to better explain what I am trying to do. If we can do business jus PM Thnxs
