How do YOU control your calcium reactor?

[TheReefGeek]

And how would you set the controller up? To controll the Ph of effluent or of the display tank?

I do method one...one day it'll be automated...I hope.

Manual control for me.

I used to control it manually, but I cant stand sitting there and counting bubbles all the time. So now I use a pH probe in the effluent and set the controller to 6.5 to 6.7, then adjust effluent flow up or down as necessary. Only took a couple days to tune this way.

This is what I have been leading towards. Why do you need a Ph probe and controller though?

Manual.

I use a controller to turn my CO2 solenoid on and off. The cheapest I found for continuous monitoring cost $110. For $10 more, I got the controller.

I have controllers for both of my calcium reactors and still do it manually and just use the controller as a monitor. Jeezz one of these days I am going to have to hook them up. I will monitor the effluent - my gro-tech calcium reactor has a port to insert the PH probe right into the body of the reactor to get a really accurate reading too!

#1 for me, I usaly adjust bubble and flow to get my output Alk about 3X higher than my desired tank Alk, then after that I just adjust the flow through the reactor to fine tune the tank Alk.
