3 kg natural pH increaser for medium pools
When the pH falls below 7.2, the water becomes aggressive: it wears down seals, tarnishes metal fittings, and reduces the lifespan of the filter and filtration system. The Puerto Verde pH increaser corrects this imbalance with a 100% natural treatment and returns the water to its optimal point.
This 3 kg size, granulated and with a dosing scoop, is designed for medium pools of around 20 to 40 m³ and for the entire swimming season.

You add pH increaser and the pH is still low? The problem is alkalinity
It is the most frequent question we receive: "I have added pH increaser and it does not rise". In almost all cases, the Total Alkalinity is below its range. Without an alkalinity of 100-150 ppm, the pH has nowhere to rest and any correction is lost in a few days.
First, the alkalinity increaser
The 3 kg size corrects the TAC of a medium pool so that the pH remains stable.

Maximum protection
A correct pH extends the life of your pool
With the pH at its ideal level, the water loses its corrosive power and stops attacking the fittings, tiles, and exposed metal elements. As a result, the need for other maintenance products is reduced and the useful life of the filtration and cleaning systems is extended.

Dose
Dose for medium pools
The general rule is 300 g (10 level scoops) per 50 m³ to raise the pH by 0.1, or what is the same, 60 g (2 scoops) per 10 m³. In spas, 15 g per m³ raises the pH by 0.2. Always do a prior analysis to know how much to correct.
