Winter time is planning time. I put a waterfall in my 1/2 acre pond and love the affect. What I am wondering about is the pool that I put at the top of the waterfall.
My thought was to have a small pool where I could keep some minnows for use in the pond. It is about 2 feet deep and 10 feet across.
this is the best picture I have. the pool is at the top.
Here is my concern and question. Since the waterfall pulls water from the pond, it is high in nutrients. That causes lots of algae in the pool since it is shallow and the water does not constantly move. I treat the pool, but it just flows into the pond and does not recycle. I want a cleaner water feature situation. Do I need to get rid of the pool and just have a river that goes to the waterfall (rocks in front)? What have others done with this situation?
