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.
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.
This pesticide is toxic to fish and aquatic invertebrates. Waters treated with this product may be hazardous to aquatic organisms. Treatment of aquatic weeds and algae can result in oxygen loss from decomposition of dead algae and weeds. This oxygen loss can cause fish and invertebrate suffocation.
It Should Not Be Done Together. 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.
After five to seven days, you can add algaecide to complete the cleaning process. Algaecide will work with the chlorine or oxidizer to kill and prevent white water mold from returning.
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. Shut your pump off and let the cloudiness settle.
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.
The algaecide in the kit can cause some foam if there is no algae in the pool to destroy – it lingers around with nothing to kill. Spring time algaecides use surfactants to work and these molecules can react with agitation to cause froth.
Best swimming pool algaecide for all pools
For an all-purpose swimming pool algaecide, we recommend Kem-Tek 60% Algaecide Concentrate. This pool and spa algaecide contains 60% of its active ingredient, polyquaternium WSCP. It's effective at removing most types of algae and preventing them from returning.
1. Shock the pool with chlorine every day until all the green is gone (possibly 3 to 4 days). 2. Run the filter 24 hours a day and backwash every day until the green and then cloudiness is gone (usually up to 7 days, sometimes as long as 2 weeks depending on the filter).
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.
Add pool algaecide at a rate of 12 ounces per 5,000 gallons of pool water.
Swimming pool foam can be a huge distraction in and outside of your pool. Foam, or bubbles, make the water feel sticky and can make swimming uncomfortable for some. Good news for the kids, though, a foamy pool is safe to swim in. Still, we always recommend getting rid of the foam as soon as possible.
Foaming in a pool means there are high levels of total dissolved solids (TDS) in the water. TDS are the measure of solid matter that has liquefied. Foreign solids like oil, soil, and dirt dissolve in pools. High levels of TDS makes pool water look cloudy and can even make it taste salty.
You're Using the Wrong Algaecide
To save money, many families opt to use cheap, low-grade algaecide in their pool. Unfortunately, along with being poor at keeping algae at bay, these chemicals also produce surface foaming. To prevent this type of foam, make sure you check the label of your algaecide.
One final note on algaecide: Contact algaecide is different from liquid algaecide. Many liquid algaecides don't work in cold water, and we don't recommend using them even in the warm months.
Shock and Chlorinate Your Pool
Shocking kills any bacteria that might linger in your pool during the winter. We recommend shocking a few days before you close the pool. If that is not possible, make sure to shock the pool the night before you close it for winter.
Correcting Common Pool Problems with Baking Soda
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.
pH Balance and Chlorine
Algaecide also works together with chlorine, helping the chlorine to be more effective against algae and bacteria.
