Very curious to see the hydrotube in action. Considering a few of these for my dream build.Getting ready to move into our new facility in last half of January start of February. Then will start the process of filling the tank. Decided to cap the 4 existing closed-loop holes down the center line with PVC plugs since its PVC bottom and then drill 4 2" holes in the 4 corners and add a Hydrotube 63 in an "H" configuration to replace the 2 Vectra pumps to power the closed loop. Corner holes will allow better flow control with the Hydrotube. I will post updates including pictures in Jan-Feb.
