Should I use SDIC granules or bleach in my swimming pool?

When maintaining pool hygiene, choosing the right pool disinfectant is key to ensuring clean and safe water. Common swimming pool disinfectants on the market include SDIC granule (sodium dichloroisocyanurate granule), bleach (sodium hypochlorite), and calcium hypochlorite. This article will conduct a detailed comparison between SDIC and sodium hypochlorite. Help you understand their characteristics and choose the best disinfectant for your pool.

Introduction to SDIC granule

SDIC granules, the full name is sodium dichloroisocyanurate granules, is an efficient and stable chlorine-containing disinfectant that is widely used in swimming pools, baths and other water treatment places. As one of the star products of professional swimming pool disinfectant manufacturers, SDIC granule have the following significant advantages:

1. High available chlorine content

The effective chlorine content in SDIC granule is generally between 56% and 62%, which has a strong bactericidal effect and can quickly eliminate bacteria, viruses and algae in the water.

2. Fast dissolution

SDIC granule can quickly dissolve in water to ensure that the disinfectant is evenly distributed in the swimming pool and avoid local concentrations that are too high or too low.

3. Good stability

Compared with bleach, SDIC granule are more resistant to light, heat and moisture, are not easily decomposed during storage, and have a longer service life.

4. Easy to store and transport

Due to its higher stability, SDIC granule are safer during storage and transportation and are less likely to cause leakage or reaction accidents.

Introduction to bleach

Bleach is a liquid disinfectant with sodium hypochlorite as the main ingredient. As a traditional disinfectant, its anti-virus principle is the same as SDIC. Both have the effect of rapid disinfection. However, sodium hypochlorite has poor stability and is easily decomposed under light and high temperature conditions. Its effective chlorine content will drop rapidly with storage time. Therefore, it needs to be used immediately after purchase, which increases trouble of daily maintenance or the difficulty of cost control.

Comparison between SDIC granule and bleach

To help you more intuitively understand the differences between the two disinfectants, the following will compare several key dimensions:

According to the actual situation, choosing a suitable pool disinfectant requires comprehensive consideration of factors such as pool size, budget, frequency of use, and ease of maintenance. Generally, we recommend that you choose SDIC. Especially for small family pools or temporary pools with limited budgets. If used as a pool shock, SDIC will also be your best choice. SDIC dissolves quickly, is easy to operate, and has a high effective chlorine content. It can quickly increase the free chlorine level of the pool.

In addition, SDIC particles are more suitable for users who want to reduce operational risks and simplify storage management. It has strong stability and is not prone to leakage or decomposition, which is more in line with the needs of home users and pool managers.

Of course, if it is a large swimming pool or public swimming pool, TCCA is recommended. Because these swimming pools have a large amount of water and high water quality requirements, TCCA’s high efficiency in sterilization, long-term stability, and slow dissolution can better meet the needs. In addition, as a professional swimming pool disinfectant manufacturer, the large-package TCCA we provide is more cost-effective and can effectively reduce operating costs.

Correct use of SDIC granule

In order to ensure the effectiveness and safety of use, the following points should be noted when using SDIC granule:

1. Calculate the dosage

Add SDIC granule according to the recommended dosage according to the amount of water in the swimming pool and the current water quality. Generally, 2-4 grams can be added for every 1000 liters of water.

2. Dissolution and placement

Pre-dissolve the SDIC particles in clean water, and then evenly sprinkle them to various areas of the swimming pool to avoid directly putting the particles into the swimming pool and causing excessive local concentration or discoloration of liner. Do not storage the prepared solution.

3. Monitor water quality

Use swimming pool water quality test strips or professional equipment to regularly test the residual chlorine content and pH value in the water to ensure that it is within a safe range.
