Looking for serious CA reactor advice

[ickmagnet]

Thanks everyone. I've set up the bubble counter and have it set to about 30 bubbles per minutes and the effluent drip rate is about the same.

OK so I've done some testing and I'll post my values. Please advise what needs to be done in terms of adjusting the Co2 and drip rate. pH controller is maintained at 6.5

Effluent test
Ca is about 450ppm
Kh is about 25
Ph - can't measure at the moment

Tank water test
Ca is below the measuring point, so below 370ppm
Kh is about 6
pH is about 8.0

With respect to the effluent, are there any adjustments that I should make? Should the Ca of the effluent be higher? How can I get the effluent Ca higher?

With regards to the tank water, should I buy some two part to get my Ca to respectable levels first? Looks like the Kh is slightly low as well.

Much appreciated everyone for your continued help with this project.
