## Summary description

Marimex AQuaMar pH+ is a 0.9 kg pool pH increaser designed to raise and stabilize swimming pool water pH. Supplied as a concentrated chemical formulation for periodic dosing, it helps maintain optimal water balance, improve sanitizer effectiveness and prevent corrosion or irritation. Suitable for routine maintenance of residential pools and hot tubs.

## Long description

Marimex AQuaMar pH+ 0.9 kg is a concentrated pool pH increaser formulated to raise and stabilize the pH level of swimming pool and hot tub water. Presented as a granular or powdered chemical formulation for periodic dosing, this product is intended for routine water balance maintenance to help maintain optimal pH, improve the efficiency of sanitizers, and reduce the risk of corrosion and skin or eye irritation.
Advantages
Marimex AQuaMar pH+ provides a reliable method to increase pH in pool water, allowing more consistent control of water chemistry. Its concentrated formula enables small, measured doses that can be added during regular maintenance. Proper pH control supports sanitizer performance and helps protect metal components, liner materials, and users from the effects of water that is too acidic.
Suitable for
Private residential swimming pools and above-ground pools
Hot tubs and spas requiring periodic pH adjustment
Routine seasonal or weekly water maintenance
Owners who use chlorine or other common pool sanitizers
When it may not be suitable
This product is intended for adjusting pH upward and is not a comprehensive water treatment on its own; it should be used as part of a broader water maintenance routine that includes sanitizer, alkalinity, and hardness control. It is not suitable for immediate correction of extreme or hazardous chemical imbalances without first testing water and following safety guidelines. For commercial pools with complex water systems or very large volumes, dosing requirements and procedures may differ from residential use.
Key specifications
Form: concentrated granular/powder formulation suitable for measured dosing
Net weight: 0.9 kg
Primary function: raises and stabilizes pool water pH
Intended use: periodic dosing for swimming pools and hot tubs
How to use
Before adding Marimex AQuaMar pH+, test the pool water with appropriate test strips or a digital tester to determine current pH and alkalinity. Calculate the required dose based on measured pH, pool volume, and the manufacturer’s dosing guidance. Dissolve the measured quantity in a bucket of pool water if recommended, then distribute evenly around the pool while the filtration system is operating. After dosing, allow circulation for several hours and retest pH, repeating treatment in small increments if necessary until the target pH is achieved.
What to consider before purchase
Confirm product suitability for your pool type (in-ground, above-ground) and volume
Have a reliable pH and alkalinity test method available to determine dosing
Store in a cool, dry place away from children and incompatible chemicals
Usage recommendations
Use small, incremental doses and retest between additions to avoid overshooting the target pH. Maintain regular testing and combine pH correction with alkalinity control for stable water chemistry. Always follow safety instructions on the label, wear appropriate protective equipment when handling pool chemicals, and keep chemicals in their original packaging.
