ph min 5kg granulate

pH min 5kg granules – powder for lowering the pH of swimming pool water

To properly disinfect the chlorine in swimming pool water, the pH value or also the acidity of the swimming pool water must be adjusted to 7,2 – 7,4. You can lower pH with pH minus 5kg of granules / powder. (Sodium bisulfate)

How much should I dose?

For lowering the acidity of your swimming pool water with 0.2 units you need 150g/10m³ water dosing. A calculation example:

• pool of 50m³ water with a pH value of 7.6
• we want to reduce the pH value to 7.2 = 0.4 units
• 0.4 = 2 x 0.2 = 2 x 150g/10m³ = 300g / 10m³ = (x5) 1500g / 50m³
• to lower the pH value by 0.4 units in a swimming pool with 50m³, you therefore need 1.5kg pH minus powder.

How does alkalinity affect pool water pH?

The alkalinity = the buffering capacity of the swimming pool water

• the higher the alkalinity of the pool water, the stronger the buffering capacity, the more pH minus powder you will need. So you may need almost double the recommended amount!
• the lower the alkalinity of the swimming pool water, the weaker the buffering capacity of your swimming pool water and the faster you will be able to influence the pH value / acidity. It is therefore also possible that you need SOMETHING less pH minus granules.

Wouldn't it be better to use liquid pH minus?

Keep in mind that in trade also very much liquid pH min and plus is available in small packages. Do not buy this, usually the product is very diluted and you are better off with powder. However, if you have one automatic pool water treatment, use liquid pH minus - sulfuric acid.

What does pH mean?

pH is the degree of acidity a good indication is this overview *:

• pH 14: Sodium Hydroxide - Liquid pH Plus (concentrated)
• pH 12: oven cleaner
• pH 9.5: Bleach - Liquid Chlorine - Chlorstabil 299B
• pH 7: pure, distilled water (neutral)
• pH 5: slightly acid rain
• pH 2.8: Coke
• pH 1: sulfuric acid (battery acid) – Liquid pH Min (concentrated)

How can I measure pH value?

It is best to measure the pH value with a Pocket pH meter from Hanna or with Test Strips.
