kalkwasser apex setup?

MACHO · Jan 22, 2023

Hey everyone I just got the bubble magnus and have never set one up on the apex. It runs a stirrer which is plugged into the apex power strip. Then has a apex pump which is put into the auto top off tank which is completely seperate from the atk which runs on it's own. how would i program the setup so that it stirs first then pumps water in. is there a calculation yall do for how much kalk needs to be dosed?

I am a kalk reactor user and I currently use an ice cap. On my unit I use the Apex to turn on the stirir every 4 hours with this code.

Fallback OFF
OSC 000:00/000:01/003:59 Then ON

I then dose Kalk based on the alkalinity demand. To start I normally test alkalinity and then test again 1 day later. If your demand is really low then you might wait a week. You can then measure the difference in alkalinity to find out how much alkalinity your tank uses in a day. Once you know the consumption, you can use a dosing calculator to find your daily dose. I then divide the dose into hourly additions. My Kamoer doser does this automatically. I just enter the daily total and then how many times I want the dose split into.
