New pond syndrome!

After installing a new filter system a few weeks ago, I thought I'd better do a water quality test. I've been using bio start type additives by the way.

Anyway, the Nitrite levels were dangerously high so I quickly carried out a 90% water change with treated water and tested again. Still dangerously high. The colour is off the scale. Very dark indeed.

Should I do another water change or just wait for the bacteria to establish?

I tested my tap water too and that gives a result of 0.1 mg/l
