I really like this idea, I may have to scrap my whole idea for that haha. Do you think it would matter if the two holes were drilled on the back side of the tank instead of the end. I don't imagine it would.
I'm going to see if I can find some clear pvc and probably go with this. It would have been cool to see the water working through the acrylic "standpipes" but this just makes way more sense lol
