5.0 out of 5 stars PH Control April 26, 2009

I've used it one time and it was very effective. Since purchasing this kit I've read a book on beginning hydroponics--apparently you can use vinegar to lower the PH and baking soda to raise it it you don't want to spend the money on this kit.

5.0 out of 5 stars Just what you need if you don't have a meter January 27, 2010
Amazon Verified Purchase
I bought this pH test kit instead of a digital pH meter. A good digital pH meter is fairly expensive and a cheap meter could have questionable accuracy. Plus, I have had experience using digital pH meters at work a few years ago, and they are just hard to deal with, not as far as using them, they are easy to use to test the pH of something, but they can easily fall out of tolerance and need to be calibrated, you don't necessarily know when the reading is off and it needs to be calibrated, as in the pH measurements you've been getting were wrong for a while and you didn't know it, the probes have to be kept wet or not depending on the model of meter, not to mention they are a sensitive electronic device and you have to just be careful with them.

So therefore, I got this pH test kit and it works great. Sure, it's a regular test kit and doesn't give you the absolute exact pH like a meter would, but if you need the pH of something to be in a particular range, as in water or nutrient solution for plants, this will certainly do the trick.

But I have to say that whatever you test probably needs to be clear or close to it, since you fill a vial half full and then put 3 to 5 drops of pH testing solution to observe the resulting color change to get the pH. In other words, I'm thinking you may not be able to test the pH of Kool Aid or tea or something, but water or water mixed with plant nutrients where the color is only slightly changed would be fine.

5.0 out of 5 stars good stuff September 17, 2009
Amazon Verified Purchase
Works very well in controlling ph levels in soil and hydro setups. The color chart and indicator solution are very easy to work with. Takes me an extra 1 minute or less to adjust ph of nute solution. Good stuff. Consider the soluble powder version of the up and down if you want it to last longer. Also you get more for less shipping

4.0 out of 5 stars Does what it says
This stuff does just as it says - changes the pH. I used 1/4 teaspoon per 2 gallons to adjust the pH of water from 7 to 6.

5.0 out of 5 stars Exactly as advertised
All I had to do was add .5ml per gallon and then shake well to get in the needed range. If you are a new user just understand that tap water ph can fluctuate. Read more

1.0 out of 5 stars -.-
The bottles came in a plastic bag. And inside the bag the bottles were open , and spilling . It ruined the instruction , and the ph label on the side of the ph tester.
