Advice please. First time using a calcium reactor. I currently dose 70 ml per day of Aquaforest 3in1. I’m going to use an Ecotech Versa pump. Thinking about starting out pumping 30ml of tank water through the reactor per minute, start PH control high meaning Carbon Doser will turn on at 7.5 and off at 7.4. One bubble every 2-3 seconds. Initially only going to reduce AF to 65 ml per day and will adjust/monitor from there. Once I get the PH down to 6.5 will adjust the amount of effluent if needed. Does this seem logical? Anything I may be missing? Thanks!

Not familiar with your equipment. I can bump it for you.

What does manufactures operations manual recommend?

How big is your aquarium? 70ml of the AF 3n1 doesn't mean anything without aquarium volume.

Are you planning to turn the carbon doser on and off based on pH of the reactor?
I think you are misunderstanding how the CaRx works as far as control, effluent flow, CO2 addition.
You won't get much alkalinity in the effluent until you are in the 6.7-6.4 pH range. It will depend a little on what you are using for media.

The best way to set it up would be to know how much alkalinity you are adding per day. Then target an effluent around 20dkh. Then you can calculate how much effluent you need at 20dkh to replace your AF dosing. Once you know that you can set your effluent and add CO2 until you hit around pH6.7 and test your effluent. From there you can tweak your CO2 bubbles to hit your target effluent dkh.

The idea is that once you get the CaRx dialed in and your tank alk is stable where you want it you can just leave everything running as is. If you need a little more alk then turn up the CO2 a little. When you start getting up to around 30ish DKH in the effluent you need to up the effluent flow so the pH doesn't get really low and turn your media to mush.
