Anyone using the Schuran Jetstream 1 or 2 with a pH Probe and controller.
The probe fits in the tube just above the tap. I am getting some irregular readings and I am finding that the Co2 builds into a pocket in the tap area which gives false readings. Today it told me the reactor was running at 6.25 when it should never get that low becuase I have the Tunze Controller set at 6.5. When I release the probe to let out the gas the pH reading climbed to 6.9.
So this means the the reactor is running on a higher pH than I want it to ie:- 6.50
but the Controller thinks it is below 6.50 and keeps the Co2 switched off.
I think I have found a flaw in the design.
Anyone got any comments or found the same as me.
