In my opinion the General Hydroponics brand is rock solid. I have used a lot of their nutrients and maintenance products and always find them to be the highest quality. This product is no exception.

If you care about PH, and you should, regular testing and re-calibration of your meter is essential. For me the 7.0 is perfect since I operate in the 5.5-6.5 PH range. I used to use the 4.0 as well to verify the calibration settings but over time found the 7.0 to be sufficient. I was checking my meter once a month or so and it was not often enough so I decided to get the larger bottle so I can test my meter more often. I use the small paper Dixie cups you use in the bathroom for kids and toss them afterwards as it's best to not reuse the solution. This bottle should last a long time.

Definitely recommend this for checking/calibrating any PH meter that has this feature.

I felt i needed to clarify what this product is used for, because of all the reviews stating they used this to ph their water or nutrient water. GH has a product called "ph up" and "ph down," and that's literally what they're for. This liquid product which is green in color is specifically for CALIBRATING YOUR DIGITAL PH METER!!! And also is suitable for using as electrode storage solution. You put this in your ph cap that your ph meter goes into and it helps preserve it and makes it so your meter doesn't take a thousand years finally deciding what the ph is. Do we all understand what this is for now??? Good!!! : )

The general hydroponics 7.0 PH solution is great for the meters that have a manual calibration screw. It’s so much easier than using the powdered packets. If you have an auto-calibrate meter, chances are, it’s set to calibrate to 6.86 I use about half of a shot glass before use on any of my pen type ph meters. This bottle lasts forever doing that way.

Works great. Tested with drop test kit and a calibrated meter and it came out to be 7.0ph.

Gives a reference point for calibrating PH meters used to check pond water for Koi fish.
