SORRY WHAT THE BEST WAY TO SETUP A KALK REACTOR
I am ATOing with kalkwasser during the 12 hours the lights ore off or dim. I use a centrifugal pump to add the kalkwasser to my sump from a 20 gallon tank. I first set up the pH-value 1 as shown below:
I set the nominal value to 8.2, since I don't want to exceed 8.2 at night. I use "pulse variable" for the "operation mode controller" so that I add kalk in short pulses (up to 13 seconds). Pause time is 8 minutes. The variable pulse is shorter (1 or 2 seconds) when pH is close to 8.2 and is longer (up to 13 seconds) when far below 8.2
Next I set my timer in the next post.
