Hi Randy,
I am getting ready to change the media in my Ca reactor to something different, most likely the effluent flow and alk concentrations will change with the media swap. I am trying to determine what the change would be, or at least how to do some measurements and calculations to get myself in the ballpark so I do not overdose the alk and burn up all my SPS.
Currently I am using ARM media in an MTC Reactor. The pH in the first chamber is 6.80, effluent is 20ml/min via a masterflex dosing pump. I am going to switch to DaStaCo media that requires the pH in the rector to be at 6.0. I am thinking I can take a sample of the effluent and measure the alk, then determine the daily alk I am adding. When I swap out the media I should be able to do the same and adjust the effluent rate until I get the same daily alk being dispensed. Sound right? Any calculations you have that I can use?
