DOS and BRS 2-Part

[Michael Hull]

Most recent measurements:

Alk - 7.9
Calcium - 401ppm

If I want to bump Alk to 8.0 - BRS calc says to add 9.6ml.

If I want to get Calcium to 420ppm - BRS Calc says to add 262ml.

What am I missing??

I mention DOS in the subject, because I'm going to integrate the Neptune DOS to automate this, but something is clearly off. My Alk drops by about .1-.2 daily right now.

Seems right to me.

Yep takes a lot more calcium solution

For me to raise my alk .5 takes me 30ML and to raise calcium 25 it is a little over 200 ML

My tank consumes .5 dkh per day and 25 ppm ca per week so it actually is pretty close to balanced 2 part of 30 ML per day. Doesn't always balance out for everyone but for me it just happens to
