Kalk dosing

[polarbear]

So I just set up my reefkeeper and connected the ATO to it. I'm running kalk in my ATO. This is my first time doing this. I calabrated the PH prob and when I added it to my tank my PH reading was 8.1. After the ATO coming on several times my PH is now at 8.27. This has been in the last 30 min. Is this normal for the PH to go up that fast? Will the kalk stable it out at 8.4? Also the ATO with kalk makes the water a little cloudy when it comes on. I have the pump about 3in off the bottom of the top off container.

Following along. Cause I want to start dosing too

I added some alk to get it up to 9dkh so that the kalk can keep it stable. PH is reading 8.43 right now.

Those are pretty big ph jumps IMO especially over just a couple hours. A little bit of cloudyness is normal, just make sure to let the kalk mix your using sit overnight so everything can settle

I thought so also. It's leveled off now. I think the problem was when I was trying to get the float switch adjusted. The water level was low so a lot of the ATO went into the tank at once which made it jump up. After adding the alk to raise the KH everything has leveled off. PH was around 8.4 before the lights went off and is setting at 8.36 now that the main lights are off and the refugium light is on. I'll cross my fingures over night that I wake up to a healthy tank.

How saturated is the ATO kalk? TSP per gallons?

I started with 4tsp in 5 gallons of water

I used a kalk reactor. Motor would kick on four times a day, but the top off was through a float for evaporative loss. Monitoring the ph was for my own maintenance requirements.

I know that there are those that run in response to the controller, successfully. However, my system would kick on when ph was low and run until it was normal, and **** off. But there was such a lag between dosing and the actual measurement that after the controller would **** off, my ph would continue to climb.

I didn't hook my ATO up to turn off when the ph was to high. I have it running on it's own. I didn't want to mess with all that. My ph is at 7.97 this morning. When the lights come on I'll see where it climbs to
