comments: Staged up pumps in steps to 1200 lpm / 144 bar.
Return brine weight 1.18sg until 68 m3 pumped.
At 68 m3 pumped the return brine weight decreased to 1.14sg and slightly changed color (kill pill with graphite).
Return brine weight gradually increased to 1.17sg at 73 m3 pumped.
At 77 m3 the return brine weight was back at 1.18sg.
Circulated totally 118m3, until even brine weight in/out.
