In swimming pools, disinfectants play a vital role. Chlorine-based chemicals are commonly used as disinfectants in swimming pools. Common ones include sodium dichloroisocyanurate granules, TCCA tablets, calcium hypochlorite granules or tablets, and bleach (sodium hypochlorite). Among them, NaDCC and bleach (the main component is sodium hypochlorite) are the two most common disinfectants. Although they both contain chlorine, there are significant differences in its physical form, chemical properties, and application in swimming pool disinfection.

Application of sodium dichloroisocyanurate and bleach in swimming pool disinfection
Advantages:
High safety: Solid form, not easy to leak, relatively safe to operate.
Good stability: Long storage time, not easy to decompose and become ineffective.
Accurate measurement: Easy to add in proportion to control the chlorine content in the water.
Wide application range: Can be used in various types of swimming pools.
Disadvantages:
Need to be dissolved before pouring into the swimming pool
Compared with bleach, the cost is higher.
Bleach (sodium hypochlorite)
Advantages:
Fast dissolution speed: Easy to quickly disperse in water and quickly exert disinfection effect.
Low price: Relatively low cost.
Disadvantages:
High risk: Liquid, highly corrosive and irritating, need to be handled with caution.
Poor stability: Easy to decompose, effective chlorine decreases rapidly due to environmental factors (temperature, humidity, light and storage time). When used in outdoor pools, cyanuric acid needs to be added to maintain the stability of free chlorine.
Difficulty in metering: Professional equipment and personnel are required for metering, and the error is large.
Storage and transportation requirements are high.
Sodium dichloroisocyanurate is best used in the following situations:
Shock treatment: If your pool needs shock treatment, SDIC is your first choice. SDIC is particularly effective for this due to its concentrated nature. You can quickly increase the chlorine level without adding a lot of product, so it is an effective choice to provide your pool with the necessary chlorine level.
Targeted application: If your pool has algae growth or specific problem areas, SDIC allows for targeted application. Spraying the granules directly onto the problem area provides concentrated treatment where it is needed.
Regular maintenance: SDIC may be a more suitable choice for people who frequently chlorinate their pool. The easy-to-use and safer application may be ideal for families and families with children. Its long shelf life ensures that it can maintain its effectiveness even if stored for a long time. The best pool NaDCC dissolves quickly and works immediately!
Precautions
Safety first: Whether using NaDCC or bleach, you must strictly follow the safe operating procedures and wear protective equipment.
Regular testing: Regularly test the residual chlorine content in the water to ensure the disinfection effect.
Comprehensive consideration: When choosing a disinfectant, you should consider the size of the swimming pool, water quality, budget and other factors.
NaDCC and bleach are both common swimming pool disinfectants, each with its own advantages and disadvantages. Choosing a suitable disinfectant requires comprehensive consideration based on the specific conditions of the swimming pool. Generally speaking, NaDCC is more suitable for outdoor open-air pools or when shock is required. When considering the use, storage and transportation conditions at the same time, swimming pool chemical suppliers recommend the use of sodium dichloroisocyanurate.
