It uses a sensor to detect the CO2 level in the reactor, enabling the solenoid when CO2 is needed. If your GEO works fine I don't know why you would want to change. It is simpler to setup than the GEO.

Sorry for late reply.


Solenoid can fail in situation when saltwater will flow thru open solenoid valve(it will rust mechanism inside).
It can happen when Customer is chaining co2 bottle and solenoid is still connected to controller - after placing on the floor(below water level) due siphon effect water will flow out by the solenoid and after some days/weeks it will stop closing/opening..

I've got a one way flow valve between the solenoid and reactor

My geo is working. I’m just tired of dealing with the clogging effluent, then having to change the bubble count, etc. just looking at options as well as dosing.

Same here, I went ahead and installed a check valve to prevent backflow into solenoid and CO2 regulator.

Pacific Sun Calc Feeder Pro AC mini satisfied reefer!

First of all, I want to thank the contributors to the thread who have helped Pacific Sun make a better product. I have read the entire thread and saw the comments/suggestions provided and the changes made to improve the product. I certainly sympatize with the early users but thankful for the sacrifices you all have made. So I went ahead and took the plunge and purchased the AC Mini for my 100 gal SPS tank. Received the reactor in a week and a half and arrived perfectly packaged and no damage. Despite the instructions, Pacific Sun answered my questions before I started the setup and I was able to get it setup in less than two hours (cleaning the chambers, filling them with media and water all the way up to powering on and getting the mixing chamber saturated with CO2). I was apprehensive at first but it was much much easer than I thought. Certainly easier than the traditional reactor! As of today, it has been running for two weeks and I have completely stopped my dosing. What I like the best is the ease of adjusting the effluent flow to dial in alkalinity. This is what convinced me to purchase the product. I also purchased a degassing chamber and my tank pH has not been affected. That is a huge plus and was worth purchasing. Thank you again to the fellow reefers and many thanks to Pacific Sun for being so responsive in answering all my questions!

@bobusc83 did you use a CaRx prior to this setup?

Yes, I had a geo 618, carbon doser, and a medical grade dosing pump for effluent. Night and day difference in usability. Much easier to dial in and control effluent rate

Your had effluent issues with the dosing pump too?

Sorry, did not mean to imply that. I simply adjust the pump flow rate incrementally to adjust/keep up with alk. Solenoid valve and optical sensor keeps mixing chamber co2 level to dissolve the media.

I mean on your previous set up. Did you have issues with your peri pump?

On my previous setup, I started with dosing two part then transitioned to the calcium reactor mentioned above. At least for me it was not simple or intuitive enough for me to get the effluent rate properly adjusted along with the bubble count to get consistent alk level. Perhaps it was the novice in me. For me the pac sun reactor is ideal for me: simple. Just my humble opinion.

Hi all,

How is the solenoid connected to the controller? Has anyone had issues with the optical sensor getting gunked up? Seems like that would be a common issue?

Solenoid valve is controlled by CalcFeeder controller.
About opticals sensor - there is no any special issue with that, usually(depending from flow/media type) every 6-12 months you should clean it if controller can't read proper water level inside mixing chamber.
For example - in my home reactor I never cleaned it(since two years). We had one or two reports where Customers used media wich started dissolving in higher pH and media "melted" - it was clogging optical sensor , but any typical media like CarbiSea ARM, natural crushed corals, Knopp Koralith, AM Hydrocarbonat work great...

Thanks for getting back to me! So is the solenoid valve connected to the controller via a plug?

Yes it is. The solenoid is powered and controlled by the controller.
