We had a quote for a system speced out for our pond. It was nearly $7,000. That was way over our budget.

Question: Is it advisable to put in a smaller unit in order to provide at least some aeration? Or is that pointless? Are there units we can build on over time?

Backstory: We have serious suspended algae issues and a worsening FA issue. We had the water tested and have an extremely high phosphorous level. The biologists who visited the pond thought the high nutrient levels were a result of the leaf litter on the pond bottom. The pond is 40 years old and surrounded by trees along much of the banks.
