The Best General Hydroponics pH Kit

General Hydroponics Review
General Hydroponics is a company that is known for providing various types of products that help to monitor and manage pH levels, and this is one of their best kits because it is the entire package. It includes an indicator and vial that will allow you to test the pH levels in your soil or water accurately. This is important because many pHs up and down solutions do not come with the indicator, which means that you have to purchase an indicator separately from the solutions.
This control kit is designed to be easy to use and follow to help get your pH levels where they need to be. All you have to do is fill the test tube halfway with the nutrient you wish to test and add a few drops of the pH test indicator to the vial. Once you have done this, you will just have to observe what the color results are and compare them to see if you need to use the pH up or the pH down solution provided in the kit. It is that simple.
Professional and Technical Issues
is important to note that this product does contain citric acid and ammonium phosphate and not just phosphoric acid. We have found that there is a more complete breakdown of organic nutrients when using this kit instead of just phosphoric acid. Also, we find that adding a cup of ammonium phosphate to our nutrient solution every two weeks keeps our plants healthier and prevents deficiencies.
Inorganic vs Organic Fertilizers
Organic fertilizers are generally preferred over inorganic because they are derived from natural sources (plants or animals) as opposed to being derived from fossil fuels. General Hydroponics states on their website: “Today, most chemical fertilizers sold commercially contain nitrogen gas (N2), which was ‘fixed’, or converted into a substance containing carbon and hydrogen by an ammonia-oxidizing bacterium called an ‘azotobacter.’ The amino acids and proteins that are broken down by the bacteria into ammonia are called ‘organic’.”
Use Recommendation
Maintaining a comfortable pH for your crops is elementary with the General Hydroponics pH Control Kit. Just fill a test-tube halfway with your nutrient solution and add a few drops of our handy pH Test Indicator to see what happens. If the liquid’s green, something isn’t right – try more “pH Up” until it turns red, or less “pH Down” if it’s pink. In this kit, you’ll find 8 oz of both ‘Up’ and ‘Down’, as well as enough indicator fluid to do about 100 tests.
This compact kit is ideal for anyone from beginner hydroculture gardeners who just want to keep their growing routine simple; advanced hobbyists looking to achieve perfect balance.
Pros
- Easy to use.
- Includes pH up and down formula.
- Includes vial and indicator for testing.
Cons
- Acid and ammonium phosphate and not just phosphoric acid.

What Is Hydroponic pH Up and Down Used For?
Hydroponic pH up and down has a simple use. The pH down solution is generally 30% phosphoric acid, and the pH up solution is generally 30% potassium hydroxide. Changing the pH levels in soil can help to reduce the shock to plants during a gradual environmental change, and these two solutions are meant to either raise or lower the pH in the hydroponics system used in soils for gardening.
It will essentially replace some of the minerals that were used up by planting different types of plants in the soil because depending on the plants, the pH in the soil can go up or down, and the solutions are designed to gradually bring the pH back to a normal level, which is ideally around 5.8 to 6.5 for most types of plants.

How To Use pH Up and Down
pH up and down solutions are designed to help raise or lower pH levels in the soil. To use these solutions, it is best to read the instructions provided by the manufacturer of the particular solutions you have purchased, but that doesn’t change the overall “how”. Basically, you need to use an indicator solution to first find out the current pH levels of your soil.
Once you have this, you will mix either the up solution or the down solution into a gallon of water. It is important to note that the amount of solution per gallon can vary. Therefore, you will want to read the instructions with your specific kit to ensure that you are using the proper ratio.
How To Bring pH Up and Chlorine Down
This is generally an issue with pools. Many people mess up and put in way too much chlorine, which can be dangerous to swimmers. However, you can use pH up in the water to help lower the amount of chlorine in the water. Make sure that you first check the water with a chlorine strip to ensure that the levels are too high. Then, you can use the pH up formula to increase the pH levels, which will naturally bring down the chlorine levels in the pool water.
How To Bring pH Up and Down With Household Items
There are all sorts of pH up and down formulas available on the market, but what if you don’t have access to any of them or don’t have the need to buy a large quantity? Luckily for you, there are a few household products that you can use to help manage your pH levels, but it is important to note that they might not be as effective as some of the actual pH up and down solutions available.
Acid is needed to help bring pH levels up, and if you are looking for a common household solution, then you could use either vinegar or lemon juice to accomplish this. However, if you have a high pH level, then your best bet is to use baking soda mixed with a gallon of what to help and bring the pH up. These can both be effective, but you need to know the current pH levels in your soil and your water to properly fix the pH levels in your soil.
How To Bring pH Up and Alkalunty Down
Even for experts, this can be a huge issue because the truth is, the materials that you use to lower or raise pH levels will also do the same to the alkalinity levels, as well. Therefore, this is not really a viable thing to do even when using pH up correctly. You could possibly get this effect by using a household product, instead of a straight pH-up solution.
How To Keep pH Up and Carbonate Hardness Down
This generally has to do with people that are trying to maintain pH levels in an aquarium. There are a few different things that you can do in order to achieve this goal. First, you can use acid buffers to help and convert KH to CO2, and if that does not work or you still need to adjust it, then you can try mixing distilled water with tap water and adding it to your aquarium.
How To Use General Hydroponics pH Control Kit
General Hydroponics pH control kit is one of the easier kits on the market to use. It has easy-to-follow instructions, but the basics behind using it are to find out your current pH levels and then follow the instructions with the product to help adjust the pH levels with either their pH up solution or their pH down solution depending on your current pH levels and readings.

What is ph up and down made of?
The companies that sell the main ingredient in ph up and down claim it is potassium hydroxide. This sounds like lye/caustic but it is not. Lye is sodium hydroxide, caustic soda (sodium hydroxide) will burn your hands when you touch it with exposed skin and cause chemical burns if swallowed. Potassium hydroxide however only causes a mild irritation to your eyes – nothing more than that, AND DOESN’T BURN YOUR SKIN OR CAUSE CHEMICAL BURNS! It is used as an industrial chemical for removing manganese from steel rolling mills etc.
where can i buy ph up and down?
We recommend ordering from an online store.
How to bring ph up and alkalinity down?
The process for ammonium production is very simple. The system must be clean enough to allow nitrification, which is the conversion of ammonia into nitrite and then into nitrate. Once ammonia is produced by the bacteria in your filtering substraight or gravel , it will rise to about 10 ppm before getting converted; thus, you can tell if your filter is fully cycled within a few days if your ph starts rising. To maximize this effect, make sure that there are plenty of surface areas like PVC pipe pieces (don’t forget to sterilize them!) or holes drilled in your container where oxygenated water can come into contact with the media where bacteria lives. There should also be an efficient biofilter for these bacteria living on surfaces to extract nutrients and make your water clean enough to keep nitrifying bacteria alive; I recommend a micron filter with great amount of surface area.
I have not yet used Atlas since I am still looking on the internet for the finest method. When I ordered it, it appeared to be very simple (for example: How much solution to combine with a gallon depending on your present pH), but there is just a bottle of pH Up and a bottle of pH Down. It would be really great if there was some information for novices.
I can’t believe no one has pointed this out, but you gave just the opposite information which could be disaster for someone not paying attention… in your assessment of general hydroponics you wrote this (please correct)
