Why is my pool dark blue?

Dark pool water may be caused by high levels of manganese in the fill water. This can cause discoloration of the water to a dark blue, purple or black clear color. This can stain the surfaces of the pool with black or purple marks, which can be very unsightly.

Why is my pool very blue?

Water Turns Light Blue

“You notice the blue effect when you have a large volume of water because of the way molecules are slightly absorbing light from the red end of the spectrum,” Coxon says. The deeper the water, the more blue it appears. He also points out that the same thing happens under artificial light.

How do you get blue pool water clear?

Why is my pool blue but not clear?

Poor filtration

If your filter performance is compromised, your pool is going to be not only cloudy but also dirty as the water becomes stagnant. 90% of cloudy pools can be linked to poor filtration due to a clogged filter, a dying pump or simply due to not running it for long enough.

Does shock turn pool blue?

Always run the pump when shocking the pool and allow it to circulate for 24 hours. The water should then be a blue or cloudy blue color. Test the water 24 hours after shocking and start adjusting pH and alkalinity levels. The chlorine will still be elevated, but over a few days, it should stabilize.

What happens if you put too much shock in a pool?

Although, if you overdo the shock treatment, you risk getting green hair from chlorine due to the excess chlorine oxidizing the copper in the water. You can execute a shock treatment with a few different types of pool shock, just be mindful of how much you're using.

Does chlorine turn water blue?

Of course, chlorine also keeps the water clear, which lets the light do it's job and make it look blue.

How long does it take for pool to clear after shock?

A pool filter should be run for a minimum of 6 hours after shocking a swimming pool. This is to allow the filter to clean the water and give the shock enough time to fully mix with the pool water. Running the filter after shocking for 24 hours to 7 days is necessary if the pool has a large amount of algae.

Why is my pool blue but cloudy?

Pool water with a high total alkalinity (TA) is often associated with cloudiness. This is because it can cause an imbalance in the pH levels and lead to calcium scaling. Typically if your TA is higher than 200 ppm, you're at risk of a cloudy pool and just like imbalanced pH levels, your chlorine will be less effective.

Will too much chlorine make 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.

How do you know if your pool has too much 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.

How can I make my pool water clear naturally?

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity.

Why can't I get my pool water clear?

Pool chemicals could be out of balance or the pH might be off. Chlorine levels and the right pH are key to keeping a pool clear. If a pool's pump or the filter isn't working right, the water may look murkier than usual. Storms or increased rainfall can affect your pool.

What color should my pool water be?

There are two primary water colors for your swimming pool, blue and green, and the shades of blue or green are determined by numerous factors. The main determiner for water color is the background dye in the finish. If you want green water, the finish should be green, brown or tan.

Will baking soda clear a green pool?

Will baking soda clear a green pool? No. Baking soda will only raise your alkalinity and pH levels and this will not kill algae. Chlorine is what kills algae.

Will Shock clear a cloudy pool?

Poor water chemistry causes most cases of cloudy pool water. Test your water to make sure it's properly balanced. Chlorine issues often cause hazy-looking water. Adding a recommended dose of pool shock to your pool can clear it right up.

Can you swim in a cloudy pool after shocking?

Wait until the chlorine level in the water drops down to 1-4 parts per million (ppm) before allowing swimmers back into the pool. If the water still looks a little cloudy after the shock treatment, you may want to use a water clarifier before allowing swimmers back into the pool.

Is it OK to swim in a cloudy pool?

You had your heart set on a dip in the pool, but now you are wondering if cloudy pools are safe. The quick answer is, 'NO!" Cloudy pools are not safe, and no one should be allowed to swim in a cloudy pool until it is cleared up.

Is pool shock the same as chlorine?

Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock.

Should I run the filter when I shock the pool?

Run the filtration system

While shocking your pool will help kill any germs any algae, it won't actually get rid of them; for that, you need your filter. So be sure to run your pool filter for at least 24 hours.

Should I backwash after shocking pool?

Steps for Preventing Algae

If your pool is used frequently, shock it at least once a week. Clean or backwash your filter regularly. Run your pool pump for at least 10 hours per day to completely circulate the water.

How long does it take for a pool to turn blue?

You need to raise the level of your chlorine – shock the pool – and maintain that high level until all the algae is dead. This may take 3 to 4 days.

What color is pool blue?

A splash of green animates this crisp medium blue. LRV, or Light Reflectance Value, is a measurement commonly used by design professionals—such as architects and interior designers—that expresses the percentage of light reflected from a surface.

How do I change my pool from green to blue?

Can I shock pool 2 days in a row?

Shocking your pool for two days in a row is a valid and recommended strategy to kill and get rid of algae. In fact, the reason why algae comes back quickly is that the chlorine levels were not high enough for long enough to kill it off properly.
