That’s a good point Bill about the shoreline weeds. I haven’t seen many weeds in our 70x70 pond, but it is only 3 years old so perhaps there hasn’t been enough time yet. Perhaps I could help add pond dye if needed?

If we were to go with this donut shape, what spacing on the diffusers would you recommend?

If I do 5 diffusers that would put the diffusers 175’ apart from each other, with each one responsible for turning 700,000 gallons. What do you think about this?
