No shade

So would you suggest more plants also?

Yes, plants that flower will help with phosphate removal.
Also, pick up a phosphate test kit.

Beautiful pond!
I agree with other members, I'd definitely add more plants.
I'd also keep an eye on the fish load, and I know how difficult it can be to part with fish, but if we overlook overcrowding eventually nature will make the cut for us
