VISIBLE ALGAE GROWTH: Add an initial dose of 97 to 128 oz of CLOROX® Pool&Spa™ Algaecide + 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.
We recommend waiting at least 15 minutes to swim after adding algaecide to your swimming pool. Most algaecides are perfectly safe to swim with.
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.
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.
In addition to adding algaecide after shocking your pool, you should add algaecide to your pool water when closing down for the year. Dark, humid weather is a prime time for algae growth, and you do not want any surprises when opening it up again.
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.
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.
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.
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.
OVERVIEW. Clorox® Pool&Spa™ Algaecide + Clarifier prevents and treats pool algae and includes a built in clarifier to keep water clear. Being one step ahead of algae is crucial because as algae grows, chlorine must work harder to keep your pool clean.
If your pool is just mildly cloudy and you are not in a rush to clean it out, a clarifier may be your best bet. A clarifier requires less work and less water but can take to two to three days to achieve the results you are looking for.
To treat pool water made cloudy by a lack of chlorine, simply keep adding chlorine to the water until the water maintains a chlorine residual of 2ppm or more. If you suspect that the cloudiness is caused by poor water balance, simply add a pH/alkalinity decreasing chemical until the water comes into balance.
When should Pool Clarifiers be Used? Pool Clarifiers are not meant to be used all season long, but are quite helpful at pool opening, after an algae bloom, or battles with cloudy pool water. Follow label directions, but most pools can be retreated after 5-7 days, with a lower dosage than initially used.
It will make those particles stick together so they will sink and then can be vacuumed (just like flocculant). This stuff does absolutely work for that purpose and will clear up your water in those instances. However, if your cloudy water is being caused by organics or algae, clarifier will not do anything.
ADD POOL CLARIFIER
Your pool water should have turned from green to a cloudy blue/grey colour. This is a good thing! The change in your pool water colour means that you have successfully eliminated the algae and can now clean it out of your pool.
The presence of too much algaecide can lead to a foamy pool water. Small bubbles will begin to be produced as the water is pushed through the return jet and back into the pool. Do not confuse these bubbles and foam with another common problem, which is air in your pool lines.
Are algaecides safe for my pond plants and fish? Algaecide treatments, no matter what chemical is used, can be safe for both fish and plants if used correctly. The chemicals in algacides, although potent, do not directly harm your fish. Fish that die from the use of algaecides die from oxygen deprivation.
It's important to note that you should not try to vacuum green pool water until you have removed any and all organic debris using a pool net, and have added the proper chemicals to the water, and done proper brushing so that the green algae has visibly settled to the bottom of your swimming pool.
Chlorine—yep, your typical sanitizer—is much more effective at killing algae than algaecide is. Even if your water gets cloudy and your walls get slimy, chlorine can still kill it. That's because chlorine oxidizes bacteria and single-celled algae, which means they trade electrons.
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.
It's not a good idea to use pool shock at the same time as clarifier. Some clarifiers are polymer based and the shock can act to break up the polymer causing the clarifier to be ineffective. It's best to shock your pool before and wait a day or two before adding clarifier.
It could take up to 24 hours for the pool water to clear after treating with Algaecide. We suggest waiting at least 48-72 hours before adding any more items (shock, algaecide, etc) to your pool water. If there are no signs of clearing you may need to shock your pool or drain and refill with fresh water.
