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.
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.
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.
Low levels of chlorine or bromine may not be able to kill algae spores, resulting in algae blooms and cloudy pool water.
How long does it take for a cloudy pool to clear? Depending on how cloudy your water is, it may take 2-3 days for your water to clear. If you're using a clarifier, you'll need to run your filter 24/7, keep your water chemistry balanced, and add the proper amount of water clarifier every other day until it's clear.
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.
Cloudy or milky water after shocking is normal, and the water should clear up within an hour or so. Just make sure your pump and filter are running properly. If you add algaecide, keep in mind that some algaecide contains copper, which can actually make a pool cloudy.
Excessive levels of pool chemicals can cause your water to become cloudy. High pH, high alkalinity, high chlorine or other sanitisers, and high calcium hardness are all common culprits.
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.
Shock your pool water weekly to remove contaminants and clear up cloudy water. Add a preventative dose of an algaecide to your pool every week after shocking. Algaecides not only kill algae—they can prevent its growth as well.
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.
pH Balance and Chlorine
Algaecide also works together with chlorine, helping the chlorine to be more effective against algae and bacteria.
Now it's time to wait a while.
Give the shock a good 12 to 24 hours to work it's magic. If the algae hasn't cleared up after 24-48 hours, clean and brush the pool and add another shock treatment.
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).
Run your filtration system for eight hours every day over summer. Back-wash it if you have a sand filter and clean cartridges with Filtrite Filter Cleaner and Degreaser. Add 50 grams of Sanit-eezy Performance per 10,000 litres of pool water. No-one should swim for at least 30 minutes after this.
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.
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.
pH Up is sodium carbonate which will increase both pH AND Total Alkalinity (TA). If your water is close to being saturated with calcium carbonate already, then adding this product can not only cloud the water, but it will remain cloudy for some time.
Green discoloration in a swimming pool is caused by the growth of algae, a type of green aquatic plant that floats on the surface of water. Algae usually flourishes in warm water but can still take over your pool in winter if given half a chance.
