3rd chamber on CO2 reactor?

[shiftline]

I drilled a hole in the lid. Then tapped in threads and added one here

Probe holder was a waterproof wire connector from the hardware store. Was a tight fit!




The tests of outputs weew just from dripping into a cup with a ph probe

Gents, consider using the finest calcium carbonate media you can for your second or final chamber. This should increase the effectiveness of that final chamber. Also to combat lower pH associated with CA reactors dose calcium hydroxide as a suplement with a doser or in your top off water if applicable. Alternatively there are alkaline filter cartridges available for RO filters which add calcium and magnesium to your source water to bring pH back up.

I'll look into that filter add one. Avoiding kalk as I refill my top off container daily and it would be a pain to get to and mix.

I'm thinking of using one of theses as a settling pond for the effluent to offgas. Then overflow and drip into the tank. May also put an airstone in to accelerate it

I saw a couple of videos today where they used that method of airstones in an effluent bucket, let me know how yours works?

Will do! I'll give it a test tonight or tomorrow

My once super clean sump is getting so crowded! I'm going to try the big container first (prob shlold have started with the small one). To see how much it changes once it has more off had time. Then I'll add an air stone and see how it changes
So far the fresh drip is at 6.6

Okay. Swapped to smaller container first to see if a bigger settling pool makes a difference. This is like a ph test-a-thon

Nice , following along . Having same issues.
I just pu a kalk stirrer to add to my ato . But was also thinking to add second chamber after cal reactor .

So the results may be a bit skewed as I started da don tests at lunch and it's now 9pm so ph naturally drops in the tank.

Another slightly screwy thing. Ph in reactor is currently higher than my effluent output. Makes no sense unless the probe needs to be calibrated inside the reactor. It's a apex lab grade probe that was calibrated 5-6m ago when I set up the reactor.

The probe im using to test effluent is my standard In sump ph probe and it was re calibrated last week

Adding the second media tower raised the effluent approx 0.26 ph

Adding the effluent drop cup raises it about 0.1ph. smaller

Adding the airstone to the drip cup made a huge leap of 0.36 after about 10 min in the cup

Was 6.44 before air stone and its 6.81 10 min later. So the airstone has the largest effect.

Ohhh 6.83 slowly climbing! Next step will. W to try the larger settling container and see if more air space / buble time makes a difference. I suspect it might but will only be worth the extra space if it's a large difference

Photo for reference
And up to 6.85 since the last post
