I am not dosing KALK right? I am using (2) part dosing from BRS, so that is Soda Ash and Calcium Chloride. I am trying to maintain ALK at 8 dKH and Calcium at 480 ppm. This theoretically would put my PH at 8.2-8.3 in a vaccum. I know there are other things that effect PH but this is kind of the range I am looking to achieve and maintain. Here is my program:

ALK
Fallback OFF
Set OFF
OSC 000:00/001:51/058:09 Then ON
If Time 02:00 to 19:59 Then OFF
If pH > 08.30 Then OFF

I have been staying in the 7.7 - 8.0dKH range dosing 24ml every other day so what you are seeing in my program is that I dose when my lights are off for 12 hours. The first 6 hrs I dose ALK and the second 6 hrs I dose Cal. My dosers are 1.1ml / min. So at 1.51 minutes of dosing at every hour for 6 hrs I get 12.21ml daily. I am dripping right above my return pump in the sump. Every drip gets sucked right in quickly and shoots out into the tank. My PH Probe is in the sump as well but in the chamber before so it wouldn't see the change in ALK level until it cycled through the main tank correct?
