Fast Dissolving Stabiliser with Immediate Sun Protection
Lo-Chlor Instant Sunscreen Stabiliser is a concentrated liquid stabiliser specially formulated for swimming pools to protect chlorine from UV sunlight loss from the moment it is added.
This fast-dissolving liquid formulation provides immediate protection without the mess of dilutions or pre-dissolving. Unlike dry cyanuric acid, which can take many days to dissolve and begin working, Instant Sunscreen starts protecting chlorine straight away.
Used regularly, it helps reduce chlorine demand and consumption, lowers running costs, improves filtration, and supports more consistent stabiliser levels for ongoing pool water balance.

Features & Benefits
- Provides immediate protection from sunlight loss by protecting chlorine from the harsh rays of the sun from the moment it is added.
- Fast dissolving liquid formulation works straight away with no messy dilutions or pre-dissolving.
- Helps reduce chlorine demand and consumption for more efficient day-to-day pool operation.
- Helps reduce running costs by improving chlorine retention and reducing waste.
- Works efficiently in any water temperature and is suitable for all pool finishes.
- Improves filtration and supports stable water balance as part of ongoing pool care.
How It Works
Instant Sunscreen works by raising the stabiliser level in the pool water so chlorine is protected from ultraviolet sunlight loss.
It acts as a fast-dissolving liquid stabiliser that begins working as soon as it is added, helping to maintain chlorine for longer in pool water than unstabilised conditions.
It is not an acid-based stabiliser. It is a salt with a pool-friendly pH, designed to provide effective chlorine protection while supporting balanced pool care.

How to Use
