Update time (almost up to date.) SpS are doing great, I started using Kalk in my ATO about 6 weeks ago. First I used B-Ionic Buffer for a few weeks to get my levels where I wanted them, I figured out my evaporation rate and set my Reefkeeper multi-timer to run my ATO pump for 30 seconds every 25 minutes. The pump will only turn on when the tank needs water because I left the Avast ATO in the loop. Seems to be keeping my levels completely stable.
Here's a FTS
