Is there a pH controller?

[mountainman]

Ok, so I did a little more research, and the CO2 plug is actually just a 110/120V socket controlled by the ph monitor. So, that means that a solenoid valve could easily be controlled by it, allowing a drip acid injection system to be setup. I'll put up a nice tutorial when I have all the parts. What this all translates to is that an acid doser system can be setup for only about $100!

Bluefunk, blue lab also makes the trucheon which is a awfull meter. Then again the sell them in bulk for under 20 bucks usd so I guess we get what we pay for. Anyone have any more info on co2 ph adjusting. Very interesting the fish dont die from suffication.

Well, as far as the CO2 dosing, I'm pretty sure that your solution would become saturated with gas and you would not be able to adjust the ph further. All liquids have a limit to how much gas can be dissolved in them, it typically depends on pressure, temperature, and the fluid type.

So basically for organics nutes it would kill all forms of life microorganic life. Humic acid, flovic acid, calcium sulfate are all I need to stablize ph anyways.

karmaxul the truncheon is an awful meter? How so? I've been using one for 2 years now, calibration hasn't slipped.. thats bullshit. Truncheon is a reliable, accurate meter.

Ok, I've got most of what I need to build the doser, but I'm still looking for a good solenoid valve. Anyone wanna help my web search? Looking for something under $40 that I can connect 1/4" OD tubing (1/8" ID) to. 120VAC activation is preferred.

I was board so I started testing meters. With the trucheon I could add 4000ppm of epsom salt and have the meter read the same before and after on two seperate ones.

thats funny. I can add 1/4 of a teaspoon of epsom salts and the truncheon sky rockets... dunno what was wrong with yours.
