Use a pool brush to vigorously scrub any pool surfaces covered in algae, including the walls, floors, and steps. Apply a green algaecide according to the directions on the label. Let the water circulate for 24 hours, then brush the pool surfaces again. Vacuum or backwash to remove any remaining dead algae.
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.
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.
It's important to know that using pool shock and algaecide together can create bad chemical reactions if you don't take the necessary precautions. Your chlorine levels won't return to normal right after you shock your pool anyway, so we recommend waiting at least 24 hours to add algaecide.
Now is the time to add Pool Clarifier and let it circulate for 12 hours. This will clump the algae together into vaccumable pieces. Shut your pump off and let the cloudiness settle. This may take up to a few days for very cloudy pools.
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.
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
5. Can I Use Algaecide to Clear Cloudy Pool Water? You can use an algaecide to kill early stages of green algae that might make your water appear cloudy, but the best method of getting rid of algae is to scrub and clean your pool using a large leaf net, vacuum, and kill algae with liquid chlorine shock.
A nylon or rubber brush is the correct choice for scrubbing the sides of a soft-sided above-ground pool. A large pool brush makes quick work of the job, but you may need a smaller brush to clean corners. Once the particles have been removed from the sides of the pool, turn your filter back on and agitate the water.
Isothiazolines are very effective algaecides and fungicides, but only at acid to slightly alkaline pH levels. Contact time is typically 5–6 h. Dose rate is typically 50–120 mg l−1, for 1.5% active isothiazoline.
The HTH Ultimate Algae Guard is the one that is added every 90 days, it is a copper based algaecide.
It took two days but it was completely gone. Not a trace. I would so recommend this product.
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.
There are a few different types of algaecides that contain various chemicals to suppress and fight off algae. Many of them include copper or copper sulfate. It's this copper that oxidizes in the water. And when copper oxidizes it turns a green color causing your pool to look green.
Add pool algaecide at a rate of 12 ounces per 5,000 gallons of pool water.
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 growing in your pool.
Metallic algaecides are usually copper based. Copper is toxic to algae because it disrupts the photosynthesis process. The higher the percentage of copper the more effective it will be, but there may be an increased risk of staining your pool plaster or plastic pool steps, with a blue-green color.
When closing and winterizing your pool, it is important to remember to balance your pool water's chemistry prior to closing and don't forget the algaecide. Algaecide is simple and effective with one quart of winter algaecide typically enough to treat 20,000 gallons of water all winter long.
of Burn Out 35®, per 6,000 gallons of water. NOTE: Be sure to remove your cover before shocking and leave it off at least 8 hours. Use Algicide weekly by adding BioGuard® Backup Algicide. 6 ounces initially per 5,000 gallons and a a maintenance dose of .
Winter Pool Algaecide is highly effective at preventing all forms of algae. Polymer pool algaecide stays strong all winter providing dependable control of algae growth throughout the winter season. Unique winterizing algaecide is specifically formulated to fight cold weather algae for up to 5 months in a covered pool.
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.
