It has a liner but it flows through to brook. I lined it due to heavy mud
which fish would stir up cutting view of them. I have had this set up for 3
years and never a problem. should i have water tested.

Is your pond a true natural pond, mud bottom and flow through fresh water,
or a pond made to look natural, but completely recycling the water? I
think that we need to know this before we can provide useful feedback.
