What tests are you performing and what are the results? Besides ammonia &
nitrite, what's the pH and KH? Water temp? ~ jan

I haven't run a test this year yet, but when I was having the problem
last year pH was neutral and absolutely no trace of anything.

Hmmm, with a pH of 7.0, I'm betting your KH (buffer) isn't adequate. If
buffer isn't adequate, filtration/nitrogen cycle isn't efficient.

brought a pond vac today gave the pond a good clean so I let it settle
and then run a water test and post the results here.

With more complete info, we can guess better. ~ jan
