I am not quite sure what you mean by this. Do you mean you are looking for a needle valve as well as a solenoid?

OK, you wrote this back in 4/27/10
A pH controller (such as those made by Milwaukee) will allow you to determine the pH of your aquarium water on a continual basis. By hooking up the pH controller to a solenoid (which is part of your CO2 system), you can have your pH controller inject CO2 when your pH goes above a certain set point, and have it stop injecting CO2 when your pH drops below a certain set point.

In my opinion, this is completely unnecessary. I believe too much emphasis on aquarium fish requiring the "perfect pH" has been placed in our hobby, leading beginners to believe that certain fish can only be kept at a pH of 6.4, or 7.0, etc.

Do you understand that what you are talking about is a CO2 controller. It is not designed to control pH but to control the level of CO2 in a tank. Maybe this came out in the last 3 years but your thread is kind of dated and needs to look at current best practices.

If you play with chemicals you should know some chemisty.

You understand that the way it works is buy measuring the ph, right? You're not actually controlling co2 levels as you are using ph to figure out how much the co2 has altered it.

What would Honey Badger do?

For reference, I will be referring to the Milwaukee SMS122.

Milwaukee markets this as a "Smart pH/CO2 Controller", but there are other sites that market the exact same product as a "pH Controller."

I would say that it is a pH controller, and not a CO2 controller, as the probe measures pH and not CO2 (though there are CO2 probes available; if this was used, then I would call it a CO2 controller).

The SMS122 measures pH, and subsequently controls a solenoid that will either open to allow CO2 to flow, or closes a solenoid to stop CO2 from flowing. The pH is changed through this injection of CO2.

Of course, the same effect could be achieved through (say) addition of an acid that is controlled by a solenoid. Would you then call this a CO2 controller?

These are the items I found not on eBay had to go back and very very slowly your post tho Thanks!

Needle valve - MNV-4K2
Burkert solieniod- 6011
But the burkert should I go 12 or 24v leaning towards 24v?

I would not recommend the Clippard MNV-4K2, as I mentioned in my original post.

For the Burkert solenoid, either the 12V or 24V will work fine; be sure you know if it is VAC or VDC, and be sure to use the appropriate converter.

Both are VDC converter?

Some low voltage Burkerts are AC. If it is indeed AC it will say something like 24V 60hz.

No I wouldn't because the device is designed to control CO2 using CO2. If you think it can control pH then set it to a reading of 8.5 and see if you can maintain a pH of 8.5.
My CO2 controller has been set for 20 ppm and it has controlled that level for almost 5 years.

If you play with chemicals you should know some chemisty.

By maintaining a specific drop in PH.

You do realize that a thermometer doesn't measure temperature. It measures volume. So do you call it a volumeter?

Well, this is precisely what people maintaining reef aquariums do; they use a supply of kalkwasser to increase pH using a pH controller. The principle is the same, but working "opposite" to us (as we aim to decrease pH).

If you had a pH controller that could control two solenoids, one for CO2, and one for kalkwasser, then the device would still be a pH controller.

Not sure what you are getting at here - I would not say a thermometer measures volume; as temperature increases, the volume of the liquid changes, however, and we use this change in volume to get the temperature.

Are you calling a pH controller a CO2 controller because you think it is controlling CO2? There is no CO2 probe on a pH controller, so then this would technically be incorrect.

As I mentioned, if you have a pH controller that could control a supply of CO2 and kalkwasser, then it would still be called a pH controller, and not a CO2 controller.

Again, for our purposes, a pH controller only controls the pH by increasing its acidity; you are right in saying that it would be impossible for a pH controller (that only controls CO2) to influence the pH to a value of 8.5.
