reactor tunning

[gasman059]

just hooked my reactor and everything is double checked-
the solenoid i s connected to the back of the milwakee ph probe
all is ok-initial parameters were all ok.
Initial starting point-50 ml per minute and bmp 30
the ph at the milwakee probe monitor is set at 6.5(in the dial) the effluent ph at this moment is 7.7 pics
The alarm always on ??
My prevoius experiences have not included a probe.
Any suggestionshttp:///i115.photobucket.com/albums/n320/gasman059/IMG_2201.jpg[/IMG]
