Hi
@pondvideoaddict ,
That is one very cool project! I think what
@GBBUDD was getting at is that, because of the curvature going around the Gazebo, you'll have a lot of dead zones where water isn't being pushed / pulled enough to circulate well back to the bog. You would have much better circulation if you have the water going under the gazebo (which I realize creates a whole different set of problems).
You may be able to solve part of the problem of poor circulation via jets or waterfalls that push water out of the various covers, but you could also chose to
pull water into those corners, by creating an intake bay at the end of each of them.
The main thing is to keep the water flowing; visualize the pond as a deeper zone in a flowing river. You can get this flow by either pushing water or pulling it. But which you chose should take into account the direction of the prevailing wind. I have a much smaller pond--about 6.5 meters in length, not counting another 2 meters for the intake bay--and even that small an area benefits a great deal from having the intake bay positioned downwind of the rest of the pond. By the end of the day, the wind has pushed most of the floating debris out of any dead zones and over to the intake bay, where the increased flow can pull it right in. So you'll get better results by
pulling water downwind, rather than pushing it against the wind.
Happy ponding!

@GBBUDD and
@combatwombat will have some very good advice on construction and pump choice. If you need help translating
