Winter is gone, and warmer weather has arrived. The temperature is rising. The sun is bright with a golden glow. A swim in the pool sounds like a charm in this weather. But don’t jump in like this!

If your pool has been shut down for a long time, you’ll need to carry out some preparatory steps to make it ready for the next season of pure bliss. One of the most crucial tasks on that list is applying algaecides and getting rid of any algal growth in the pool.

Algae bloom is an unavoidable factor in owning a pool. In instances like these, you may believe that using algaecide to clean your pool water is the best choice. In this post, we will go over the facts concerning algaecide, how much algaecide to put in pool when opening, and everything that you need to know about using it safely.

How Much Algaecide To Put In Pool When Opening

What Is Algaecide? How Does It Work In Your Pool?

Algaecide is an available pool chemical that many pool owners apply in their routine pool maintenance. The chemical is intended to keep algae from growing in your swimming pool.

However, it may surprise you to find that algaecide is not a miracle cure for removing algal from your pool. Algaecide is, in fact, more successful as a preventive strategy than as a therapy.

The chemicals in algaecide work by producing positively charged ions when applied in the pool water. Therefore, an ion attack is directed at the negatively charged algae particles. Because algaecides do not degrade in sunlight, they remain in the water for a considerably longer period.

Why Do You Need Algaecide In Your Pool?

Perhaps you had a rainfall or a large pool party that threw off the chemistry of your pool. On the other hand, maybe you’ve been neglecting your pool’s upkeep for a while.

In any case, your pool might not be a fun place to be right now. Aside from being ugly, algae can cause a slew of issues, including water pests, allergens, diseases, and surface damage to your pool.

To keep your pool water clean, algaecide works best in conjunction with chlorine sanitizer. Algae spores are carried into the pool by wind, rain, or even human contact. Algae thrive in the presence of carbon dioxide, warm weather, and pH levels that are out of balance.

Algae-infested swimming pools may grow green water or sticky coatings that are yellow, green, pink, or black. Knowing how much algaecide to apply will assist you in keeping your swimming pool clean without the use of excessive chlorine.

Determining The Right Amount Of Algaecide For Your Pool

Add a dose of algaecide that matches the capacity of your pool’s water. It is critical to understand your pool’s capacity in gallons to appropriately determine the amount of algaecide required.

For accurate measurements, follow the manufacturer’s instructions on the algaecide bottle. The dosage will be determined by the number of gallons of water in your pool. Typically, algaecide is added at a rate of 12 ounces per 5,000 gallons of pool water.

There are various resources and calculated charts available online. You can refer to any one of those. But we strongly advise calculating the right amount of algaecide for your pool by yourself based on the custom dimensions.

Besides, the amount of algaecide you should use also depends on the type of algae. The following are the most frequent varieties of pool algae that you may see and hear about

Green algae are by far the most frequent, especially if you don’t wash your swimwear after swimming in a lake. Yellow or mustard algae, although much rarer, is a persistent and particularly bothersome uninvited pool guest.

Pink algae, often known as pink slime, is a type of bacteria frequently mixed with algae. However, black algae are the most challenging type of algae to eradicate.

Therefore, it is critical to select the proper type of algaecide besides the right amount. The finest pool algaecide may differ from person to person. It will be determined by the sort of pool, your budget, and your present needs.

  • Copper-based algaecides: The most prevalent variants are algaecides based on copper. Many copper-based compounds are insoluble in water with a pH greater than 7.
  • Quat Pool Algaecides: As microbiological disinfectants, Quat pool algaecide, also known as a Quaternary Ammonium compound, is used. They are positively charged and adhere to negatively charged algal cells. Thus, they destroy the external protective membrane after they are linked with the algae.
  • Polyquat or Quat algaecides: These are effective alternatives that are also intended to suppress pool algae growth. They are thought to be less dangerous to use than copper-based algaecides. These algaecides are non-staining.

Steps To Add Algaecide To Your Pool

There are few steps you must follow to add algaecide in your pool which are described below.

Cleaning The Filter

Before pouring algaecide in your pool, backwash it to get all the dirt out of the filter so it performs appropriately while circulating. Then, brush the walls and floors towards the main drain and vacuum as needed.

Balancing Water Ph

pH levels should be evaluated every other day, and total alkalinity should be measured once a month. The optimal pH range is 7.2–7.6 parts per million. Increase pH with soda ash or baking soda and decrease pH with muriatic acid.

For the best results, test for total alkalinity when the pH level is in this ideal range. The total alkalinity of pool water indicates how resistant the water is to pH variations.

Shocking The Pool

To kill algal growth, use a shock product such as Shock Quick 10, Shock Quick 10 plus 5, Shock Quick 15, Super Shock Quick 20, or Vinyl Pool Shock on a regular basis. Pouring shock into a bucket of water with at least a couple of gallons of water is the best way to apply it to your pool. Flow the liquid around the pool’s perimeter after it has dissolved.

Adding Oxidizer

Because a conventional shock cannot be used in a biguanide pool, adding an Oxidizer is the best alternative. When the term “oxidizer” is used about swimming pools, it refers to the usage of potassium monopersulfate to shock the pool. Potassium monopersulfate degrades organic pool pollutants while also assisting chlorine in its work.

Running The Pump

After adding an oxidizer, brush the pool and run the pump for a night. If possible, run the pump for at least 24 hours so that all the waste can be cleaned from the pool. In this situation, your pool will look the worst.

Re-Brushing The Pool

If you think you have not cleaned your pool perfectly or you have missed a spot to brush, then we would suggest brushing that place or the whole pool again. Again, take extra care so that you can be satisfied with your job.

Vacuuming The Pool

The swimming pool should be vacuumed. To remove the dead algae detritus in the pool, wait 24 hours after the initial application of algaecide. Then, if algae are still visible in the water, repeat the algaecide treatment in the pool according to the manufacturer’s directions.

Re-Cleaning The Filter

It’s a great idea to clean your filter after a thorough vacuuming and brushing. At this point, backwash your pool filter and operate the pump to ensure that all of the algae has been eliminated.

Re-Balancing The Water

Your water is now clear, the walls and floor are free of algae, and your filter has been cleansed of any dead algae. Next, re-test the water in your pool.

Test and fine-tune your pool to the following levels: Free chlorine: 1-3 ppm, pH: 7.2–7.6, alkalinity: 80–120 ppm, and calcium hardness: 200–400 ppm Proper water balance in your pool is critical for keeping the water clean and free of algae.

Best Time To Put Algaecide And Swim Afterwards In Your Pool

Algaecide should be administered after each shock treatment to give your chlorine a greater chance of working its magic. Make sure to shock your pool first. Then, when the chlorine levels return to normal, administer the appropriate amount of algaecide to different locations around your pool while your pump is operating. This will aid in the circulation of the algaecide.

It’s critical to understand that combining pool shock and algaecide might result in harmful chemical reactions if proper safeguards are not taken. This is because your chlorine levels will not return to normal immediately after shocking your pool. Therefore, we suggest waiting at least 24 hours before adding algaecide.

Allow around 30 minutes after the algaecide treatment before letting anyone swim. To remove dead algae detritus from the pool, vacuum it 24 hours after the initial application of algaecide. Before swimming in the pool, you should wait another 24 hours at the very least.

Bottom Line

Understanding the correct answers to how much algaecide to put in the pool when opening is critical. It will assist you in ensuring that your pool remains algae-free.

We have gone over what algaecide is, how to use it successfully, and how to properly dispose of algal when it decides to raise its ugly head. We also gave details about the various types of pool algaecide and how much to apply. This way, you can make an informed decision when it comes time to clean your pool.
