When the pH of water is too high, it is often said that it is "basic". If this happens (in the water that comes out of the taps, in the pool, in the aquarium or even in the hose), the liquid can have several problems - since the excess of certain chemicals is harmful to humans, animals and plants. Luckily, it's not difficult to control the situation! Read the tips below to learn more.

Steps

Method 1 of 4: Lowering the pH of Home Water

Lower the pH of Water Step 1

Step 1. Add lemon juice to a glass of water to adjust its pH

If you don't want to treat the water directly at the source and don't mind feeling a slight lemony taste in the liquid, pour two or three drops of the juice into a glass of water containing 240 milliliters. The juice naturally lowers the pH, making the water more acidic.

  • You can also place lemon slices in the water to accentuate the aroma and flavor.
  • The same is true when using pure citric acid.

Step 2. Install a tap water filter to lower the pH directly at the source

The filter removes minerals that raise pH from the water, including sodium, fluorine and potassium. The way of installation depends on the model, the most common being with screws. Finally, the filter is activated whenever someone turns on the faucet.

  • Purchase the filter at any home improvement or home improvement store.
  • Most household water filters purify around 40 L of water per hour.

Step 3. Use food acids to reduce the pH of very large volumes of water

Some acids, such as phosphoric, sulfuric and lactic, are used in the processing of certain food products, such as fermentation. Read the labels carefully, as the proportion of these products in relation to water varies from one to another and according to the ideal pH for the case.

Buy these acids at supermarkets, home improvement stores and the like

Did you know?

As strange as it may seem to add acid to water, the product leaves harmless compounds when it neutralizes the solution. Anyway, always read the labels to know how to use everything!

Step 4. Install an acid injection system to solve more persistent problems

The acid injection system takes a pH level reading from where the situation is most tense. Then, he injects the necessary acids into the liquid so that it comes out neutralized from the tap. Hire a professional to do the installation.

The system and installation can be a little expensive, but they are the best solutions for those who have the problem at home

Method 2 of 4: Lowering the pH of Garden Water

Lower the pH of Water Step 5

Step 1. Research the ideal water pH level for each plant you are growing

Before trying to reduce the pH of the water, find out if plants prefer acidic environments. This is the case with azaleas and sweet potatoes, for example. However, other cultivars and plants, such as beets, prefer the soil to be neutral or slightly basic.

The ideal average pH for most plants is 5, 5 to 7, 0

Lower the pH of Water Step 6

Step 2. Put lemon juice in the watering can for a natural solution

By adding 1/8 teaspoon (0.6 ml) of lemon juice to about 4 L of water, you can lower the pH of it by about 1.5. Lemon juice can be fresh or industrialized, but it should be 100% pure.

  • You can also use citric acid, but you may have to dissolve it in some water first.
  • If you plan to measure the pH of the water again, add the lemon juice and wait about five minutes while it spreads.

Step 3. Add vinegar to the water so you don't have to spend a lot of money

Add 1 tablespoon (15 ml) of white vinegar for every 4 L of water. The product's natural acidity helps to neutralize the basicity of the water, lowering the pH from 7, 5 to 7, 7 to 5, 8 to 6, 0.

The pH of vinegar ranges from 2.0 to 3.0, while that of lemon juice is on average 2.0. Therefore, the two products have a very similar effect

Method 3 of 4: Lowering the pH of Pool Water

Lower the pH of Water Step 8

Step 1. Add hydrochloric acid to the pool to make a quick adjustment

Hydrochloric acid is widely used to lower the pH of swimming pools. Depending on the form of the product, you will either have to apply it directly to water or dilute it in a separate bucket first. In either case, hold the can (or other container with the acid) close to the surface of the water so it doesn't come in contact with your skin. Also, apply acid directly to the face-down return jet so that it circulates faster.

  • Buy hydrochloric acid at nautical supply stores.
  • Read the acid label carefully to find the right amount.
  • Add a little less than you think is necessary, wait four hours and do another test. Then, if necessary, add more of the product.

Heads up:

hydrochloric acid and sodium bisulfate are corrosive. Read the labels and follow the instructions exactly. In addition, only use the products in ventilated areas with personal protective equipment and, after application, wait at least four hours before entering the pool.

Lower the pH of Water Step 9

Step 2. Use sodium bisulfate if you prefer a less strong solution

Sodium bisulfate is usually sold in granulated form. Depending on the manufacturer's instructions, you have to add it directly to water or dissolve it in a separate bucket. Bisulfate helps to lower and stabilize the pool's pH and is therefore a more interesting option for frequent maintenance.

  • Despite being dangerous, sodium bisulfate is not as strong as hydrochloric acid. However, it takes longer to take effect and usually lowers the total basicity index (IBT) more than necessary.
  • Follow label directions and pH readings to determine how much bisulfate you have to add to the pool.
  • Sodium bisulfate is also sold in marine supply stores.

Step 3. Install a CO system2 in the pool to balance the pH longer.

Some CO systems2 are automatic - that is, they monitor the pool's pH and release CO2 as necessary. Others are manuals; in these cases, you'll have to check the pH levels every day and adjust the CO release2 when necessary. Talk to a subject matter expert to choose the ideal option.

  • CO systems2 they can be quite expensive, depending on location, size and power. Still, it's better to invest in them than buy more temporary solutions.
Lower the pH of Water Step 11

Step 4. Use a kit to measure pool pH at least twice a week

The chemicals used in the pool acquire unstable levels when not properly treated. Therefore, it is essential to test the pool's pH two or three times a week, even after balancing it. You can use specific test strips, but the DPD test kit generates more accurate results. It measures the pH and IBT of the water, as well as the chlorine levels, which makes the whole process easier.

  • Skin oils, sunscreen, creams and dirt affect the pH of the pool water. If you use it every day, get this test done even more often.
  • Buy these kits at marine supply stores.

Method 4 of 4: Lowering the pH of an Aquarium

Lower the pH of Water Step 12

Step 1. Install a CO pump2 for lower the pH of an aquarium temporarily.

You can use a CO firecracker2 to lower the pH of the aquarium for a while, even more if it rose suddenly. However, this alternative is expensive and has a temporary effect.

  • With price2 for aquariums in nautical stores and some pet stores.

Heads up:

aquarium fish can get a shock if you adjust the pH too quickly. To prevent this from happening, take them out of the water before using the pump.

Lower the pH of Water Step 13

Step 2. Use a reverse osmosis filter if your aquarium is large

The reverse osmosis filter is a very useful equipment, capable of removing up to 99% of the water contaminants without affecting the ions that are good for the fish. As it is these contaminants that raise the pH, the accessory naturally lowers the levels.

The reverse osmosis filter is inexpensive, but it takes up a lot of space (and therefore ideal for large aquariums)

Lower the pH of Water Step 14

Step 3. Place branches and other wood debris in the aquarium to filter the water naturally

In addition to making the aquarium more beautiful, these products filter the water and help lower and stabilize the pH. Finally, fish also like this addition.

  • Branches and other wood and plant debris can discolor the aquarium water. To prevent this from happening, leave the products in a bucket of water for a few days before transferring them to the aquarium itself.
  • Do not use products made specifically for reptile tanks. They can contain chemicals harmful to fish.
  • Even small pieces of wood help filter the water. Therefore, choose some that do not disturb the structure of the aquarium.
Lower the pH of Water Step 15

Step 4. Add peat to the aquarium filter

As the peat pieces can stick to each other and end up disappearing when you clean the aquarium, it is better to put them in a small screen bag inside the filter. The product helps to lower the pH naturally. Determine the optimal amount according to the size of the aquarium.

  • Peat can also discolor aquarium water. So, leave it in a bucket of water for a few days before putting it in the filter.
  • The amount of peat depends on the size of the aquarium and the ideal pH level. Experiment until you reach the ideal option.
  • Buy peat at pet shops or nautical supply stores.
Lower the pH of Water Step 16

Step 5. Add two or three beach almond leaves to the aquarium if you prefer a simple solution

The leaves of this tree contain certain chemicals that filter out contaminants from the water. This not only lowers and stabilizes the pH, but it can even cure certain diseases that affect fish!

The tannins present in the leaves of the beach almond tree can change the color of the water slightly, but not as much as peat and wood

Lower the pH of Water Step 17

Step 6. Remove dead corals from the aquarium

If you have difficulty lowering the pH of the aquarium, it may be that the substrate is getting in the way. Having corals makes the whole structure more beautiful, but it ends up increasing the pH levels of the water. Therefore, only use it if you have fish of species that prefer basic environments.
