Kalk question

[kynan]

Setting up a kalk set up with a versa on my 280g system, I’d estimate maybe 200 gallons total water absent the rock work and equipment. Want to address ph drop from 8.33 to 7.95 overnight with a continuous drip. I’m not sure how to get the dosing started and don’t want a risk of overdosing. I keep my kh right around 8.8 solid, and calcium about 435. How many ml should I be dosing either by continuous drip or per hour?

I would use a controller with pH and dosing. Even if just at night, that'll prevent you from nuking things. In fact, use 2 pH probes!

Still dosing Red Sea, have a bunch of Randy’s recipe mixed up , just haven’t switched over yet. May do so this weekend.

If you know how much you are dosing we can determine a roughly matching kalkwasser dose.

I’m dosing 87ml across 24 hours.

87 mL of Red Sea Foundation B has the same alk as 2.0 gallons of kalkwasser.
