It is not safe to swim in a pool with algae. Algae growth means that the pool water has become contaminated, and bacteria and other microorganisms can also exceed the standard, increasing the risk of infections such as skin itch, pinkeye, and cholera. In addition, algae growth can make the swimming pool surface very slippery, increasing the risk of swimmers slipping and falling in and out of the pool. Therefore, when algae appears in the pool, algae-killing and disinfection measures should be taken in time to ensure the safety of water quality.
Here are some specific steps and suggestions
1. Physical Methods
You can use tools to get algae floating on the water out of the pool, meanwhile, use a pool brush to thoroughly brush the walls and bottom of the pool to remove attached algae. In particular, some nooks and crannies are the most serious areas of algae. When scrubbing the pool, please avoid using tools that can scratch the surface of the pool. Also, after brushing, there will be so much algae residue in the pool, then suck them away with an underwater vacuum cleaner.
2. Test the FC and pH
The balance of pool chemicals is crucial to provide a stable environment for subsequent disinfectants and algicides to work. The normal range of free chlorine (FC) is 1-4 ppm, and the pH range is between 7.2 and 7.8.
3. Pool Shock Treatment
When there is the high combined chlorine level in the pool, you should add Sodium Dichloroisocyanurate (NaDCC) or Calcium Hypochlorite (CHC) to shock your pool, thereby restoring the disinfection effect of chlorine, which can help the algicide work better. Chlorine in the pool reacting with urine and sweat from swimmers will produce chloroamine, that is, combined chlorine, which is also the cause of the unpleasant smell from swimming pools.
4. Add Algicides
When the chlorine level in the pool returns to the normal range, you can choose the appropriate algicide according to the actual pool condition and the type of algae. Our company offers a variety of algicides chemicals, including Super Algicide, Strong Algicide, Quarter Algicide, Blue Algicide, etc., which effectively inhibit the growth of algae and bacteria to create a safe swimming environment. When handling algicides, strictly follow the product instructions and recommended dosage to avoid the water quality deterioration caused by excessive use.
5. Keep the Equipment Running
After that, keep the circulation system running continuously to remove dead algae and suspended matter in the pool. The good filtration system operation plays an important role in restoring water quality.
6. Retest the Water Quality
After removing algae, retest and adjust the pH, total alkalinity and other pool indexes to ensure that the water quality remains within the appropriate range.
7. Backwash the Sand Filters
After the pool is clear, be sure to backwash your sand filters. Backwashing can remove the accumulated algae and pollutants in the sand filter and restore its filtering effect. The sand filter needs to be backwashed per one to two weeks.
