OK got my Stock Tank all set up and tested the water fittings. Photo. Used the Skippy Bio Filter site and modified it somewhat. I went into the drain plug and chased the threads clean thru so I could add a fitting on the inside. Went thru a one way check valve so the tub would not drain back into the pond if the pump was not working. Also will not have to fit or cutout for the PVC pipe if it came from the top. See next picture.
