On one side, there is decorative slate tiling
that has been cemented into place. If this aspect was the culprit, why
would it take well over a year to show up?
........... run some water over it and collect it on the other side, pH it.

Nitrates is not one of the tests available to me
through the kit and the local pond place which has been guiding me,
also has not nitrate testing available.
...... nitrate is really important... it builds up if there isnt enough green stuff
growing and removing it.

I have a pump that's rated for a pond twice this size (per my
contractor) and use a natural filtration (bio-filter) with regular
applications (14-day intervals) of the good bacteria flakes. I have 3
koi, 3 small goldfish, and one huge tadpole.
......... stop adding the bacteria flakes. some of these bacterial additives produce
quite a bit of hydrogen sulfide. you really need to check the nitrates. Ingrid
