Dazzle’s Ultra Shock is a fast-dissolving, formulated chlorine-based shock treatment in a 950 gram 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 20C, 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.
