It's usually just a temporary reaction as the sanitizer works its magic, and doesn't always indicate a problem. But if the cloudy water persists long after you've shocked the pool, you're likely having an issue with water balance, circulation, or filtration.
Thirdly, tripple-shock the pool using stronger Chlorine like In The Swim calcium hypochlorite (3pounds for 10k gallons) to kill all the algae; depending on the number of algae in the pool, it may take 2-3 days for the pool to clear up. The filter should run 24 hours a day for faster results.
1) After shock - Sometimes pool water looks cloudy right after you apply shock granules such as cal-hypo, or liquid shock, but rest assured it's only temporary. This could be due to change in water balance – meaning your pool water temporarily goes off balance when adding these products.
Issues such as bacterial infections and skin issues can occur if you swim in water with algae. Algae will remain in your pool after shock if you've had insufficient chlorine and an overabundance of metal elements in the pool water. Therefore, to start the cleaning process.
Not to worry, this is normal and should resolve itself in a day or so as the chlorine level drops. Just keep your filter running in the meantime. If it doesn't clear up, either your filter-system is compromised, the rest of your water chemistry is out of whack, or you're using some cheap-ass, low-grade shock.
For the most part, yes. It can be unattractive and it should be addressed, but it is mostly safe to swim in cloudy water. The only exception would be if the pool is cloudy because there are too many chemicals in it. This pool water would be unsafe to swim in and should be avoided.
Shock the pool with a high level of chlorine or bromine to rapidly return the pool water to a balanced level. Imbalanced alkalinity and pH also could result in cloudy water, and it can be a safety hazard.
The water's pH may be too low or too high.
Lower than 7 indicates an acidic pool, but higher than 7.8 is too alkaline. A pool measuring at either extreme will likely be cloudy. High pH often indicates excess calcium deposits, and low pH often indicates more chloramine and less free chlorine.
If the chlorine smell is very strong, however, you may soon spot “red-eyed” swimmers emerging from the pool. That's when the pool water is assumed to have “too much chlorine” in it. Ironically, a strong chemical smell around the pool and “swimmer red eye” may be signs that there is not enough chlorine in the water.
But excessive exposure to chlorine can cause sickness and injuries, including rashes, coughing, nose or throat pain, eye irritation and bouts of asthma, health experts warn. Instructions for safely chlorinating a pool usually call for a maximum of four parts per million when people are in the pool.
When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there's not enough. But be careful—adding too much chlorine in pool water can cause those metals to oxidize and turn the pool a different shade of green.
Chlorine at high levels is corrosive so it's not a matter of if, but when. In particular, the chlorine dissolves the rubber and corrodes the plastic parts of pool cleaners, pumps and filters. It can also damage pool heater internals, as well as valves and rubber seals. This damage can be expensive.
After Shocking Your Pool
It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours. It is always best to test first!
It is important to know what exactly bleach is before you put it in your pool. Household bleach, Clorox and liquid chlorine can all be used to sanitize a pool. They are all types of chlorine. Household bleaches such as Clorox usually contain about 5-6% available chlorine, about half that of pool liquid chlorine.
If you test your pool water and can't get a chlorine reading, it may be due to your pool's high demand for chlorine. A high chlorine demand (sometimes referred as chlorine lock), simply means that although your water may appear clear and balanced, the chlorine in your pool is ineffective.
A pool turns green when there is algae in the water. There are several reasons why algae could grow, but it is most commonly caused by prolonged exposure to the sun, rain and temperature spikes. These factors affect the chemical balance of the pool and result in the pool turning cloudy and/or green.
Pool water turns green because of algae in the water. Algae can grow rapidly, particularly when it's warm like Summer, which is why it can surprise you overnight. This generally comes down to an imbalance or lack of chlorine in the water.
Baking Soda and Green, Blue, or Yellow Algae
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.
Using baking soda will not actually lower your pool's chlorine level. If your ph is way too low it may. Prevent corrosion and damage to pool equipment; To raise your ph levels, it can be as simple as adding seven to nine pounds of baking soda to your pool water.
High concentrations of chlorine (above 1.5 ppm) will attack the liner and bleach it, thus damaging it. Any level below this range will weaken its ability to kill off bacteria.
What you may not know is that hydrogen peroxide is a powerful oxidizer that can be combined with ultraviolet light to disinfect swimming pools. The combination of ultraviolet disinfection with hydrogen peroxide allows pool owners to safely eliminate all chlorine in their pool or spa.
Chlorine issues often cause cloudy water. Adding a recommended dose of pool shock to your pool can clear it right up. Poor circulation or filtration can contribute to cloudy water. Make sure your pump and filter are working properly.
