Does anyone use a ph controller for Co2?

I'm going without the ph controller for now, just ordered a milwuakee regulator with Needle valve, bubble counter, solenoid, and 10' of co2 tubing for $82.99 ( I feel like that's a good price). I got a 5 lb co2 cylinder filled from my local Airgas for $76.00 (refills are $13.00 Swapped tank). Just have to order a drop checker (about 10 bucks) and a check valve and I think I'm ready to go, Hopefully for under $200.00.

I got to admit I wanted Rex's regulator but I had to settle for the milwuakee. I hope i won't regret it.
 
The kh ph chart always had me at 70 ppm of co2. It was really at 30 ppm when checked with a drop checker. As has been stated above, the controller can keep your ph at a particular level, but you have no real way of knowing the real amount of co2 without a drop checker. I think the bubble counter and drop checker is the best way to determine proper co2 levels.
 
Just got all my equipment for pressurized Co2 together for the first time ( the drop checker I got off ebay took awhile to get here from Hong Kong ). Anyhow, after some research I got some distilled water and some baking soda from the store and am looking for an easy recipe for 4dk water.

I have a gram scale. How much baking soda should it take for say , 250ml of water ? Anyone have any ideas?

I cant wait to start up my Co2!
 
Nice link.

unfortunately, my math in my earlier post was off :wall: I apologize.

On the bright side, .3 grams of baking soda mixed with 250 ml of distilled water = 40 kh solution. Which I then took 25 ml of said solution and 225 ml of distilled water ( if you've got another 250 ml bottle lying around its perfect) to make a perfect 4dk solution.
