Description
Introducing the Deep Blue Pro Shock Chlorine Granules, a superior solution designed for hot tubs, spas, and swimming pools to maintain crystal-clear and safe water for your ultimate relaxation and enjoyment. These highly effective Shock Chlorine Granules are specially formulated to target and eliminate contaminants such as bacteria, algae, and chloramines, ensuring the pristine quality of your spa water.
When it comes to water maintenance, the significance of Shock or Super Chlorination cannot be emphasized enough. Whether you are filling your spa for the first time, reopening it after a period of inactivity, or simply dealing with heavy usage, these Shock Chlorine Granules are your go-to remedy. By administering a Shock treatment, you can effectively reset and revitalize your spa water, creating a clean and hygienic environment for you to unwind in.
Regular maintenance is crucial for keeping your spa water in optimal condition. We recommend Shock treating your spa water at least every 2 weeks, or more frequently if your spa sees heavy usage. These granules are specifically designed for hot tubs, as they dissolve quickly and efficiently in warm water, ensuring rapid and thorough distribution throughout the spa.
While primarily intended for hot tubs and spas, these Shock Chlorine Granules can also be used in swimming pools to achieve similar sanitation benefits. For swimming pool use, we advise pre-dissolving the granules in warm water before adding them to the pool water, as this promotes optimal dispersion, quicker action, and the best effectiveness.
One of the key advantages of the Deep Blue Shock Chlorine Granules is their convenience and ease of use. With varying tub sizes, you can rest assured that you have an ample supply of high-quality Shock Chlorine on hand whenever your water needs a refresh. The granular form allows for quick application and fast dissolving, saving you time and effort in maintaining your spa.
By incorporating these Shock Chlorine Granules into your spa maintenance routine, you are investing in the longevity and performance of your hot tub or spa. Say goodbye to cloudy or odorous water and hello to a pristine and inviting spa environment that you can enjoy with peace of mind.
Enhance your spa experience with the Deep Blue Shock Chlorine Granules – the reliable and effective solution for maintaining clean, clear, and healthy swimming pool and spa water. Trust in the power of Shock Chlorination to keep your spa water free from impurities, allowing you to relax and rejuvenate in a hygienic and inviting setting.
Choose quality, choose convenience, choose the Deep Blue Shock Chlorine Granules for your swimming pool, hot tub, or spa maintenance needs. Experience the difference that superior Shock Chlorine treatment can make in elevating your spa water to new levels of purity and freshness.
USAGE INSTRUCTIONS: Prior to using this product, adjust the pH levels to the ideal range of 7.2 to promote bather comfort, plant protection, and effective chemical use. Maintain free chlorine residuals within the range 1-3mg/l (ppm) for pools and 3-5mg/l (ppm) for spas. Freshly filled spas or those left without use for a period of time will require an initial start-up dose of free chlorine of 10mg/l (ppm) for pools and 20mg/l (ppm) for spas. This product may be applied directly to spas where temperatures exceed 30 degrees. For swimming pools or if below this temperature, pre-dissolve this product in a clean plastic container to a maximum rate of 10g of product per 0.2 gallons (1 Litre) of warm water. Stir well to ensure the product is fully dissolved to prevent any bleaching of the pool liner. Add the resulting solution to the water while the pump(s) are turned on, near the water inlets to aid distribution. Repeat dose application if necessary to achieve levels as shown above.
SHOCK DOSE RATES: Small Spa 1000 litres (220 Gallons) of water – add 20g to increase chlorine level by 10mg/l (ppm) or 40g to increase chlorine level by 20mg/l (ppm) for spas. Large Spa 1500 litres (330 Gallons) of water – add 30g to increase chlorine level by 10mg/l (ppm) or 60g to increase chlorine level by 20mg/l (ppm) for spas. Small pool 40,000 litres (8,800 Gallons) of water – add 800g to increase chlorine level by 10mg/l (ppm) for pools. Large pool 60,000 litres (13,200 Gallons) of water – add 1200g to increase chlorine level by 10mg/l (ppm) for pools.
