Ground probe

Gary LeCompte · Aug 6, 2019

I just got my first Triton test back from Triton.
They say I have a very high level of chromium.
The only metal I think I have in my tank would be my ground probe.
It is many years old because I have been out of the hobby for a long time and I'm using the probe I had from many years ago.
Would anyone think this could be my problem with high Chromium levels?

Did you use Mortar to glue your rock together by chance?

All of the modern ground probes are made from titanium. Since yours is older, I'm not sure what it could be made of. If it is stainless steel it could be the source.
