Royal Pool & Spa pH Minus 14% - 5 kg
Liquid concentrate with 14% sulphuric acid for lowering and stabilising the pH of water in pools and hot tubs. 5 kg HDPE canister.
Automatic control of high pH
A liquid product based on 14% sulphuric acid for automatically lowering and stabilising water pH. It helps maintain the ideal range in which disinfection works more effectively and equipment is protected from limescale.
Stable pH without manual dosing
The liquid form is suitable for dosing pumps and automatic control systems that continuously monitor pH and add the required amount of product.
Lowers high pH
The acidic component helps return high water pH to the recommended operating range.
Supports disinfection
Correct pH allows both chlorine and chlorine-free disinfection to work more consistently and effectively.
Reduces deposits
Balanced pH helps reduce cloudiness, limescale and mineral deposits in the pool.
Protects equipment
Helps protect filtration, pipework, jets, heating elements and heat exchangers.
Automatically according to the measured value
The required amount depends on the current pH, water volume, alkalinity and dosing-system settings.
Set the control system according to the requirements of the disinfection used and the type of operation.
The dosing pump adds the product according to the current value measured by the probe.
Regularly verify probe function and the actual pH using a manual test or calibrated meter.
Use with automatic dosing
The dosing equipment should be installed and set up by a suitably qualified person.
Check the alkalinity
Before starting automatic control, set water alkalinity to 80–120 ppm.
Measure the initial pH
Verify the actual pH with an independent test and compare it with the probe reading.
Connect the suction line
Insert the dosing pump suction hose into the original container using a suitable suction assembly.
Set the controller
Set the required target value and maximum safe dosing amount.
Dose into the circulation system
The product must be injected into flowing water at the designated point in the equipment circuit.
Check regularly
Check the actual pH, probe condition, controller calibration, hoses, connections and product consumption.
What does the measured pH mean?
| pH value | Water condition | Possible risk | Recommended action |
|---|---|---|---|
| Below 6.5 | Water too acidic | Corrosion and possible equipment damage | Stop pH Minus and use pH Plus |
| 6,8–7,2 | Ideal range | Chemicals work optimally | Maintain with automatic control |
| Above 7.6 | High pH | Cloudiness, deposits and reduced disinfection effectiveness | Check control and dosing |
| Above 8.0 | Significantly high pH | Limescale and reduced chemical effectiveness | Lower in a controlled, gradual manner |
