I'll have to ask the pond guy exactly what he was testing for but just mentioned he would take water samples and send it to a lab where they would come back with recommendations based on the results.
I wonder how the constant use of river water to keep the pond at a certain level impacts things with the pond. Last Spring we had a ton of critters pumped into the pond that lived well for weeks. Baby gar, green sunfish, tons of frogs,etc. But as I wrote before, ever since the draining, refilling and added aerators, nothing much survives. We saw almost all the bream and mosquito minnows die as well as all the tadpoles and frogs.
What I've been told and read online suggest aeration should not cause any issues unless the pond was already established and was not introduced correctly (ie, just turned on and left that way). Not sure what else it could be.
We do have to pump water in every week or so we run the pump overnight. It has been pretty dry in our state this winter. I attached a couple of drone pics to show the pond. Duck weed is making a comeback.
Soon the frogs will be coming to the pond in droves, hopefully the pond isn't now a pool of death for them.
Not sure where to go next if this situation doesn't improve.
