You’ll notice I didn’t mention alkalinity decreaser. Most major pool chemical companies do not produce it and here are the reasons why:

If your pH and alkalinity are low, alkalinity increaser will raise both. You may need to add a little pH increaser if the pH doesn’t reach 7.4 – like fine tuning an instrument.

If your pH and alkalinity are both high, pH decreaser will lower both.

If just your alkalinity is high, your pH will also be high and you can use pH decreaser.

If your pool is properly balanced at all times, it will make your pool’s sanitizer work more effectively – especially chlorine.

Sanitisation

The most common form of pool sanitizer is chlorine, but there are others you can use, including:

• Salt
• Stabilised Chlorine
• Minerals

Chlorine Levels

The Ideal Chlorine Levels ranges from 1 ppm to 3 ppm.Chlorine is an extremely effective bacteria and algae killer, and cost effective.

There are a few ways you can introduce chlorine into the pool water, including:

• Chlorine tablets
• Chlorine granular or powdered chlorine
• Salt Chlorine Generator: turns regular table salt into chlorine
