Kalk in Top Off

[Canadian]

Thanks untamed.

I grabbed an Aqua Lifter this weekend to replace my MJ 1200 as the ATO pump. I also grabbed some kalk. I'm going to try running the kalk in my ATO as this is going to be an SPS dominated tank. I'll run the ATO on a timer to only turn on at night. I'm anticipating that in pretty short order the kalk will eventually be insufficient. I'll then run a Liter Meter III with 2-part to make up the difference. If I run into any difficulties due to instability caused by variability in evaporation rate then I'll stop putting kalk in the top off water and rely solely on the 2-part.
