I'm looking at Calcium reactors for stability of dkh . I currently run trident / dos.
What do you guys recommend ?

2 stage?I run one on my 120. Very stable with little to no maintenence.
Also, I run no ph probe or controller.
They are worth the $'s and will last a lifetime if you get a quality 2 stage regulator, imo.
I read a little is that KalwasserI think an auto doser is simpler and you can get a pH boost depending on what you use. The calcium reactor is cool from a sciencey view point.
I modified a 6" skims media reactor and run it reverse flow with no feed pump like the Tunze reactors. I just count bubbles and measure effluent.The new ones are too fancy and expensive for my tastes. I have an old workhorse i got over 10 years ago. One external pump, no dosing pump or ph monitors, and its gravity fed.
So for me well worth the stability. I use one outlet and set the drip rate and co2 bubble count.
Im even so cheap that other than magnesium media, i just use crushed course carib sea aragonite substrate for media. Been working great for years.
But i dont know i would do it again with current prices and all the pumps and monitors and gear. Too much
Thats what i would do if mine sh*** the bed....I modified a 6" skims media reactor and run it reverse flow with no feed pump like the Tumze reactors. I just count bubbles and measure effluent.
Also if your carx is setup correctly the ph of your tank is not affected.
Sorry - how is it adding 7L of effluent a day with PH of 6.2 to the tank with 400L does not affect the PH?I modified a 6" skims media reactor and run it reverse flow with no feed pump like the Tumze reactors. I just count bubbles and measure effluent.
Also if your carx is setup correctly the ph of your tank is not affected.
On my system once bubble rate is set it never changes unless I change it.I used to run a doser but switched to a DIY 2-chamber reactor.. The build thread is here:
Project CaRx: DIY Calcium Reactor + DIY Controller + DIY Peristaltic Pump + DIY ALK Monitor
Hey folkes, 2 large DIY projects completed this year and now I am sitting idle.. What should I do next? The target for my tank is to slowly grow into an SPS dominant system. I already have 3 palm sized plating easy-going monties and have to dose about 100ml of alkainity solution daily (100mg...www.ultimatereef.net
I would not ever go back to dosing - however I think where most beginner calcium reactor users may fail is these 2 components:
- PH probe and controller switching on/off the solenoid valve. Without this you are a bit in the dark as to whether your CO2 bubble rate is adequate
- peristaltic pump, without it you don't have a good control over how much effluent you are dosing
Things you can sacrifice without too much (if any) impact:
- dual chamber (I built a dual chamber/ dual PH probe reactor - but it's an overkill)
Things to think about - you will be dosing effluent with low PH (my stage-2 effluent has PH 6.2) so generally you PH will go down when the reactor is on.
the ph is always high in my tank. If there is extra co2 its gobbled up by my enormous mass of chaetoI modified a 6" skims media reactor and run it reverse flow with no feed pump like the Tumze reactors. I just count bubbles and measure effluent.
Also if your carx is setup correctly the ph of your tank is not affected.
The fact that you don't have PH issue is not indicative that adding CaRx effluent does not impact PH. I don't have PH isssue because I counter CaRx PH drop with Kalk. But that does not mean that CarX does not affect PH. It just means I have to take extra care to elevate PH back to where it should be.. Simple maths..On my system once bubble rate is set it never changes unless I change it.
Same with effluent although it will vary slightly when the tubing gets covered in junk. But thats an indicator to clean it maybe every 6 months.
Never had an issue with tank ph running this way.
Most friends run your way and they have had more issues than me.
Both work but setting your first one up manually helps you understand whats happening in your system, imo.
In my sytem ph in my tank is the same as it was when I dosed 2 part.Sorry - how is it adding 7L of effluent a day with PH of 6.2 to the tank with 400L does not affect the PH?
The other thing you may have never understood is the media you are using, Some media will melt at PH 7.3 and some will need to be driven hard at PH 6.0. I use Rowalith and therefore have to drive it really hard. There is a big difference between adding effluent of PH 7.3 versus PH 6.0.On my system once bubble rate is set it never changes unless I change it.

I dont dose anything to counter the ph. I always have high ph. My tank is also in a basement without open windows. Been like that for about a decadeThe fact that you don't have PH issue is not indicative that adding CaRx effluent does not impact PH. I don't have PH isssue because I counter CaRx PH drop with Kalk.

Not going to argue but I do disagree as many do that run no ph probe or controller have no issues with tank ph.The fact that you don't have PH issue is not indicative that adding CaRx effluent does not impact PH.

I run carx 24/7 and also refugium is lit 24/7. Stable as granite.I dont dose anything to counter the ph. I always have high ph. My tank is also in a basement without open windows. Been like that for about a decade
Carx effluent is how i keep ph stable.
I understand as a chemical engineer for 20 years I have a pretty good grasp of my system.The other thing you may have never understood is the media you are using, Some media will melt at PH 7.3 and some will need to be driven hard at PH 6.0. I use Rowalith and therefore have to drive it really hard. There is a big difference between adding effluent of PH 7.3 versus PH 6.0.
