Your ph is 8.4? Well, that is my norm in my pond. Test it in the morning and then again in the afternoon and see what you get.
I have quite a few plants in my pond but maybe not quite as many as you. Also I have basically three filters and my water turns over at least once an hour. I have a mechanical/bio filter with a built in UV light. I have filtration by vegitation in the top of my pond. And I have a bag of charcoal that sits inside one of my water features. The water runs through that.
