Generally I'm pretty good at figuring this stuff out, but this one is racking my brain. I'm currently running my CaRx using a MasterFlex pump so I can get a very accurate delivery of effluent to maintain Alk and Calcium. I'm trying to see if I can dial in the ml/min that I would need to set the pump to hold Alk or raise it. I realize this will not be perfect, but close enough is good enough for now.

Here are my measurements:
- In 630 mins - ALK dropped .17 (from 8.01 -> 7.84)
- Effluent is measured at 14.22 (Hanna)
- Effluent is being delivered at 24 ml/min
- tank is approximately 170 gallons

So is it possible to calculate the rate to deliver effluent to maintain Alk (assuming everything else is constant)?
