pH pool too high: Lower in 3 simple steps

Many pool owners have the problem with too high a pH in the pool.

Therefore, pH sinker is a sought-after pool chemical.

There are a few ways to lower the pH pool.

But let’s get to the root cause first:

How can it be that the pool pH is too high?

Some causes are known, such as high alkalinity. Incorrectly used chemicals or algaecides in the pool also lead to the increased pH value in the pool,pond pump protection cage too much chemistry makes the pH value in the pool seem frighteningly high. It is sometimes important to “shock” the pool.

Before shocking can be done, a pool shock chlorination should be calculated to prevent further effort. If Cal-Hypo or calcium hypochlorite is used, this may cause the pool pH to be too high.

The pH value informs the user how acidic or alkaline the water is. If the hydrogen ions drop, the pH value automatically increases. When the pool is made ready for operation again after the winter break, carbonic acid will be in the water after filling.

By whirling the water, the carbonic acid dissolves. The acidic carbonic acid ensures that the pool pH is too high.

Foreign particles can also significantly increase the pH value.

Why should the pH value in the pool be lowered?

If the pool pH is too high, the pool users experience skin and eye irritation. Algae growth is significantly promoted by the increased pH, while chlorine efficacy is reduced.

The limescale makes the water appear cloudy, which can also trigger the blockage of the pool filter.

The annoying smell is another unpleasant side effect. Lowering the pool pH is the user’s ambition for many reasons, as already explained.

The correct pH value is of utmost importance, the reasons briefly listed as keywords:

Skin and eyes become irritated

Algae grow faster

Pool flocculant no longer works properly

Limescale is intensified

Can come to annoying pool smell

Lower pool pH

Lowering the pool pH value is no problem for the pool user. Different measures make it possible to achieve the ideal pH value. The methods can be implemented in just a few steps.

Step 1: Determine the pool pH

For the time being, it is important to determine the pH value exactly. Test strips are excellent, about 10 seconds the strip is held in the water:

The color that is now visible is compared with the colors of the table that is on the container. Briefly presented in keywords:

Hold the test strip in the water,

compare the colour with the table clearly visible on the container,

now the value can be read well, the matching colors are the value.

If you prefer expensive methods for determination, you can of course realize this with a special pool tester or a pool thermometer. Most often, the owner knows the capacity of his pool, if not, there are certain formulas to know the volume of the pool.

How does this happen? The formulas are below:

Rectangular pool = length x width x average depth,

Round pool = diameter x diameter x depth x 0.78

Oval pool = length x width x depth x 0.89

Eight-shaped pool = length x width x depth x 0.85

An example:

For a rectangular pool, the following applies:

Length: 6 meters

Width: 4 meters,

Depth: 2 meters,

The invoice is 6 x 4 = 24 x 2 = 48.

The rectangular pool therefore has a volume of 48 m³.

Step 2: Calculate the required amount of pH-Minus granules

Lowering the pool pH is convenient and safe with pH minus granules. How much granules is necessary? The measured pH value is known, the ideal value is 7.2 to a maximum of 7.4.

The measured pH value serves as a basis, the user now calculates exactly how many 0.1 steps are necessary to reach the ideal value of 7.2.

An example in numbers is more vivid:

Measured value 7.6,

minus perfect pH 7.2

results in 0.4.

Four steps of 0.1 each are required.

Step 3: Add pH-Minus granules to the water

The granules are added to the water, ideally when the pool filter is active. The water must circulate to achieve the optimal effect.

We recommend the following ph-Minus granules:

A net is also helpful. The granules are evenly distributed and dissolve quickly. Lowering the pH pool with granules is preferred by users.

Reduce alternative pH with pH minus liquid

pH minus liquid also provides a remedy if the pH pool is too high. It is worth noting that only half of the liquid is necessary. At pH minus liquid is spoken of sulfuric acid, the application is similar to granules.

As an alternative to lower the pH in the pool:

It is recommended to dissolve the special liquid with water in a bucket beforehand. When poured into the pool, the liquid is automatically distributed evenly. The user should be aware that sulfuric acid is corrosive and that spraying with the liquid should be avoided.

In addition, care must be taken to ensure that the pool may not be entered for at least 4 hours after use. Although the liquid has benefits, lowering the pH pool with sulfuric acid requires careful handling.

Can the pool pH be lowered with home remedies?

If you want it very simple, you can also use vinegar. The rule of thumb explains the procedure: Reduce the pH pool by 0.2 is achieved per 1 m³ with about 100 ml of vinegar.

Briefly presented in figures:

The pH value is 7.4,

the perfect pH is 7.2,

Volume of the pool is 30 m³.

Difference 0.2 is vinegar:

100 ml x 30 gives 3000 ml.

Thus, 3 liters of vinegar are actually needed to reach the desired pH value. Experts advise against the use of vinegar, because vinegar is also a food for bacteria.

Too many bacteria are eliminated with an increased amount of chlorine, the filter system is ultimately extremely stressed.

Result

If the pool pH value is too high, this leads to massive problems. Not only the algae grow quickly, but also have to struggle with skin and eye irritation.

Too many disinfectants, best pond filter system on the other hand, spoil the bathing fun. Chemical agents are used, which are quite helpful when dosed correctly.

It is now known how the limit values of the pH value are determined. If the pool pH value is too high, the pool user must lower the pool pH value. How this happens is explained by different methods.

It makes sense to test the pool water at regular intervals and, if necessary, to initiate appropriate measures at an early stage.
