Pour the algaecide dose into the water, depositing it in several areas around the pool. Your swimming pool pump should be running at this time to help circulate the algaecide. Wait about 30 minutes before allowing anyone to swim after the algaecide application.
Add a dose of algaecide, bring your chlorine level high by shocking, and run the filter continuously until the problem clears. The next day you should vacuum up the dead algae and backwash your filter. Algae thrives in hot weather and in pools with low or no chlorine.
Run your pump overnight, or if possible, for 24 hours to clean all the debris from your pool water.
It is best to wait 30 minutes after adding it to your pool. We recommend waiting at least 15 minutes to swim after adding algaecide to your swimming pool. Most algaecides are perfectly safe to swim with. It is not recommended to swim with flocculent in your pool as it will reduce its effectiveness.
It doesn't matter how much chlorine, shock, algaecide, algae preventive or algae killer you use, the surface must be brushed to break the algae's protective surface and suspend the algae in the water so that the chemicals can do their job.
ADD POOL CLARIFIER
If your water is still green, wait another 24 hours and redo the steps from Days 1 and 2. Now is the time to add Pool Clarifier and let it circulate for 12 hours. This will clump the algae together into vaccumable pieces.
Let the water circulate for at least two hours.
Circulate the water for about 2 hours to ensure the flocculant is fully mixed in, then shut off your pump and let it sit overnight. During this time, the chemical will start to bind the particles together and settle them to the bottom of the pool.
While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
Chlorine combines with the algaecide ingredients and renders them useless. The best time to introduce an algaecide , which functions best as a preventative, is after you've shocked the pool and the chlorine level has fallen below 5 parts per million.
If you add algaecide, keep in mind that some algaecide contains copper, which can actually make a pool cloudy. If the cloudiness persists 24 hours after shocking, then it's possible that you used a poor-quality chlorine shock.
Add Algaecide After Shocking
Wait for the pH to fall to a safe level for swimming (3 ppm or below) and then add a product such as Pool Time Algicide + Clarifier in the amount recommended in the product instructions. Pour this incrementally into the water as you walk around the pool.
Algaecide should be added to your pool water on a weekly basis. Preventing algae is the key to fun in your pool. Algaecides act as a backup to your normal sanitization program and prevent algae from starting and growing in the pool. Algaecide should be added after every shock treatment.
Add an initial dose of 97 to 128 oz of Pool Time Algicide + Clarifier per 10,000 gallons of water to rid the water of algae. Thereafter, add 24 to 48 oz (per 10,000 gallons) weekly during the swimming season to prevent re-growth of algae.
Pour the algaecide dose into the water, depositing it in several areas around the pool. Your swimming pool pump should be running at this time to help circulate the algaecide. Wait about 30 minutes before allowing anyone to swim after the algaecide application.
If you add chemicals to balance the water after testing, wait a full day – or even longer – before retesting. It takes about 24 hours for the chemicals to properly circulate in order to get an effective reading from the retest. The water test will assess the pH, chlorine, total alkalinity and calcium hardness.
In a pool where algae is present, algaecides work in conjunction with chlorine to kill the algae cells. The algaecide causes the cells of the algae to burst, which destroys the plant. Different algaecides are used for different types of algae.
You can get rid of algae quickly by vacuuming and brushing your pool, balancing your pool's water chemistry, and then shocking and filtering your pool water. Just be thorough as you clean your pool surfaces. If you leave behind even a small number of algae spores, it won't be long before they regrow and bloom again.
So unless you're dealing with mustard algae or black algae, leave the algaecide on the shelf and get ready to shock the heck out of your pool. But when dealing with regular ol' green pool algae, chlorine is your best bet to kill it dead.
Algaecides. While algaecides are pretty shelf-stable and will be viable for up to five years, we only recommend getting enough to cover you for a season and a little bit for the off season.
Baking Soda and Green, Blue, or Yellow Algae
You'll need to use an algaecide to kill the algae and superchlorinate your pool to clear the water. After this treatment, test your pH and alkalinity and add baking soda to raise alkalinity to at least 100 ppm and pH to between 7.2 and 7.8.
Swimming pool clarifiers and algaecides are often grouped together, but exist for two very different reasons. What are algaecides? It is important to appreciate that swimming pool algaecides do not actually kill algae – this is instead the job of shock chlorine, which we also stock here at Pool Warehouse.
Results in 24 Hours
Non-foaming formula works fast to kill pool algae.
It's a good idea to shock the water a few days before closing the pool and then adding the algaecide the day you shut it down and cover it. It's recommended that you treat the water for algae problems before covering the pool and the same goes for any type of metal that has been sitting in the water all summer.
