I can't remember - are you going to have a bog? I saw a neat video from Ozponds about how to put a breather pipe (with a ball valve) in the bog. It prevents back flow if a check valve fails - but also allows you to play with the water flow a little. I am planning to do this in mine. It will be nice to control the speed of the water flowing through the bog and will also let me have some movement in any standing water at the bog top. In your case, with such a powerful pump, this might be a nice way to deal with any extra power without straining the pump. I have heard that just restricting flow on a bigger pump can shorten the life. (Not sure if this is true but I know someone on here will be able to comment with more accuracy!)Thank you! that is great to hear about Big Frog as I was a bit concerned when Half-off Ponds decided to swap out the pump brand without telling me. I wish I got a pump with variable control for flow reduction. I would say not getting a pump with that feature is currently my main regret of my build, but I put a ball valve in so I can restrict flow when needed. This pump moves some serious water.
