Dazzle's Ultra Shock is a fast-dissolving, formulated chlorine-based shock treatment in a 2.75kg container that is ideal for use during pool opening or closing time. It is also useful as a problem-solver, such as part of an algae destruction treatment or when clearing cloudy water due to insufficient chlorine levels. This multi-functional and pH-neutral product performs the following functions in water: shocks, clarifies, and generally enhances water.
Why use pool shock?
- A shock treatment designed specifically for swimming pool water.
- Use for pool opening and closing, periodic shock treatments and as a problem solver.
- Formulated to raise the chlorine level, clarify and enhance water.
- Dissolves fully and completely, no residues or clouding of pool water.
When to use
- Immediately after opening the pool and just prior to fall closing.
- 1 hour prior to the addition of an algicide as part of an algae destruction treatment
- Can be used when needed as a shock treatment during the primary swimming weeks of the summer.
- Immediately after inclement weather/any time water appears dull and hazy.
- Any time superchlorination (super bacteria kill) is required (fouling, vomit, etc).
How Much to use
- Add 125 g per 10,000 L of water.
- Do not use the pool after use until the chlorine residual drops to 3 ppm or less.
Application
- Remove solar blanket or cover and leave off for minimum of 8 hours.
- Operate pump and filter for minimum of 8 hours after application.
- The best time to apply is in the evening.
- Apply with pump operating by sprinkling slowly into a clean, empty skimmer (free of any other chemicals or products).
- Alternatively, the product can be broadcast over the surface of the pool (preferably in the deep end). If water temperature is less than 20°C, brush immediately after application to ensure quick dissolving of active ingredient.
- Periodically check filter pressure and backwash/clean as required.
- For fall closing, with the pump off and water lowered, pre-mix in a pail of water and pour around the edges of the deep end, if applicable. Brush the pool after addition.
