Can I Use Algaecide To Clear Cloudy Pool Water

Going Beyond Water Clarity with 3-in-1 XtraBlue® Clarifier: Clorox® Pool&Spa

You can use 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.

You should only use algaecide once in a while for preventive measures and when green algae is just starting to show upit is not useful when algae outbreak is immense and very visible.

Furthermore, if you have full green, black, or yellow algae, you may end up using a lot algaecide, which can be very expensive and the best result is not guaranteed like when you use liquid chlorine. Some algaecides may also cause foaming or deposit copper metal in your water when used in large quantities.


How Pool Filters Compare

A well-serviced swimming pool starts with the filter: Most swimming pools will turn cloudy or keep pool algae due to a poor filtration system. Filters come in different brands, types, and sizes, but there is no single filter that is the best. Rather, the best choice depends on your pool size, where it is located, and how often you use it.

Why Is My Pool Water Cloudy After Opening A Pool

Depending on how carefully you closed the pool for the winter, at the beginning of summer, you may see algae and cloudy water.

The main cause is usually imbalanced chemicals. If your water is free of algae, all you need to do is test for all the chemicals and adjust. Starting with the pH, then the chlorine, and then other chemicals after that.

If the water still appears cloudy after adjusting all the chemicals, you can try using either water clarifier to remove the debris through the filter or use pool flocculant and then vacuum to remove any particles.

Replacing The Sand In Your Filter

Sand grains used in filtering have sharp edges that help in trapping debris as water passes through the filter. The sharp edges wear with time and sand grains become ineffective in filtering the debris as needed. Because of this, sand should be replaced at least after every five years for a home swimming pool, and after two to three years for public or semi-public swimming pools.

However, sometimes a sand filter may fail to filter effectively before two years elapse, depending on how busy the pool is. Some swimming pool managers use additional filtering medium such as ZeoBrite, Pebble, and Pea gravel with the old sand to improve their effectiveness in trapping debris.

If the DE filter parts are damaged, the DE will definitely go back into the pool. If this is the case, then the problem with your DE filter may be in one of the following parts of the filter:

  • Torn Filter Grids: A hole may develop anywhere on the fabric of the grid. Ensure that you look carefully to find if there is a hole on the grid and fix it.
  • Broken Manifold: If the manifold is broken, a large amount of DE will return into the pool.
  • Broken or Missing Air Relief Strainer: A broken or missing air relief strainer will allow the DE into the pool water.
  • Bad Backwash Valve: The problem may be with backwash valve, disassemble the valve and inspect it for any damage that may be allowing DE back into the pool.
  • Broken Filter Necks: Check and ensure that your filter neck is intact, loose or broken filter necks cause DE to go back into the pool.

    If the chemistry in your pool is right then the clarifier will work. You may just need to recheck a few things and try again later. Here are some reasons the clarifier didnt take on the first try:

    • Chlorine: Recheck your chlorine levels and make sure they are not too weak or too strong. Were looking for a Goldilocks level here.
    • Filtration problems: I know you already checked it, but do me a favor and check it again. If your filter isnt functioning at its best, it may be time to have it serviced.;

    When Pool Water Temperature Rises

    Bacteria and other organisms such as algae thrive in warm water. In addition, the amount of free chlorine decreases with rising temperatures.

    Most pools are kept at a comfortable level of 86-88 °F. The temperature should be lowered to a range of 78-84 °F if there are a lot of swimmers or if the pool is used for athletic activities. You can use a pool thermometer to measure water temperature.

    If the temperature rises above the recommended levels, you should shock your pool.

    How To Quickly Fix Your Cloudy Swimming Pool Water

    No sane person will want to jump into a pool filled with cloudy pool water, more so when the water resembles a big bowl of milk! This type of water is not only scary, but theres a possibility that it might be damaging the pool as well as its circulation system. If left untreated for long, it may also start breeding dangerous bacteria.

    Before you can start implementing solutions aimed at clearing the swimming pool water, you will want to know what caused it to turn cloudy. Its the most efficient way to prevent the outbreak and spread of potentially serious illnesses. Additionally, it also ensures your pool wont sustain too much damage. Solutions recommended for use are dependent on the underlying cause.

    Shock The Pool Regularly

    As a pool owner, youve likely shocked your pool a number of times in the past.

    But exactly how often you shock your pool is important:

    • Do it too much and you might get chlorine lock
    • Dont do it enough and the effectiveness of your other pool chemicals will suffer

    So whats the magic number then?

    How often should you shock your pool?

    Shock your pool once per week. This keeps your sanitizer levels stable, which keeps your pool cleaner.

    Its also wise to shock the water after heavy use, pool parties, or storms to prevent surprise algae takeovers.

    Pools : How To Clear Cloudy Pool Water

    We all know maintaining your pool can be difficult especially if you own a big one. But after all the partying, eating, and swimming, youll have to face a process so crucial yet so taxingcleanup. Have you ever reached to the point where you can barely see the floor of the pool? Then you notice your previous clear pool water has turned cloudy and milky? A ring around the waterline of the pool might even show up unannounced! You would probably give your pool some algaecide, clarifiers, and stain removers. Unfortunately, my friend, doing so could just add fuel to the fire. Thats because adding too much clarifier wont make it clear and algaecide combined with shock is just a waste of algaecide.

    So what the heck should you do?

    Ensure that your pools chemical levels are within the recommended ranges

    pH level: ;;;;;;;;;;;;;;;;;; 7.2 7.6.

    Total Alkalinity: ;;;;;;; 80 120 ppm

    Calcium Hardness: 200 400 ppm

    Cyanuric Acid: ;;;;;;;; 25 50 ppm

    To decrease your pH level, use a pH decreaser or muriatic acid. Remember, if your pools pH level is too high, it will reduce the effectiveness of chlorine, and most of us already know that its chlorine who fights the buildup of algae. On the other hand, if your pH level is too low, increase it using a pH increaser or soda ash.

    Cloudy water can also occur if the calcium hardness level is more than 400 ppm. You can reduce the calcium base chlorine using a settling agent.

    Shock the pool

    Check the pH and alkalinity levels again

    Use a clarifier

    What Is Pool Clarifier

    Pool Logic Water Clarifier

    Sometimes, the little nasty things that create a cloudy pool are just too small for your filter to capture. They pass through the filters medium and head right back into the water.

    Pool clarifier contains polymers that act as coagulants on these tiny particles. When you add a clarifier to cloudy water, all those tiny particles clump together into bigger particles your filter can capture and keep from reentering the pool.

    Note: Its usually perfectly safe to swim in a cloudy pool. Just keep in mind that visibility underwater will be limited, and opening your eyes underwater may cause irritation. For safety and comfort, we highly recommend skipping the swim until youve cleared the water.

    How To Backwash A Sand Filter

  • Empty the skimmers so that trapped leaves and debris do not get back into the pool after backwashing is finished.
  • Turn off the pump and empty the pump trap basket.
  • Ensure that the cutoff valvein the filter is opened prior to backwashing, if the filter has one, to prevent it from blowing up when pressure accumulates.
  • Put the backwash valve on “backwash” and turn the pump on; let it run until the water in the sight glass turns clear.
  • After the water in the sight glass turns clear, turn the pump off and switch the backwash valve to “rinse” and let it run until the sight glass runs clear. Alternatively, If the filter has a plunger valve, skip to step 6.
  • Turn the pump off and put the backwash valve in the filter position.
  • Turn the filter back on.
  • Turn the Pump Off Before Moving the Backwash Valve Handle

    Important: Always turn the pump off before moving the backwash valve handle to avoid personal injury and equipment damage.
