How To Clean A Green Pool In 24 Hours
The Aim of This Post is to share with you how to clean a green pool in 24 hours, not the standard 5-6 days!
The color green is a symbol of prosperity but it has absolutely no place in your swimming pool. If a pool is looking green, it means that there’s an overgrowth of algae in it. While common green algae is not detrimental to humans, it certainly is not the most inviting phenomenon under the Sun.
While the algae itself does not harm humans, the bacteria that feed on it definitely can. Also, algae can cause some serious damage to your pool’s equipment and lead to thousands in repair costs. Slimy algae attaches itself to pool surfaces and makes them extremely slippery. This can lead to falls and accidents, thereby jeopardizing swimmers’ safety.
If left untreated, algae can wreak total havoc in a pool and make the water go black. Instead of being a soothing place for fun and relaxation, the pool becomes disgustingly repulsive.
Often, it can take up to 5 days to clean up a green pool. We are going to try to do it in less than 24 hours.

So why did your pool become green in the first place?
Algae is incredibly stubborn and can grow even in inhospitable environments. Green algae , known scientifically as chlorophyta, loves warm and humid places. It derives its green color from the pigment chlorophyll.
It is almost impossible to prevent algae from gaining entry into the pool. If you take your family along for a barbecue/picnic by a lake, algae from the lake will attach itself onto swimwear and toys. If these items are used in your swimming pool without be sanitized first, you’ll have inadvertently introduced algae into the pool.
Algae can also enter the pool via cleaning tools, filters which contain bits of algae from a previous cleaning or via wind and rainwater.
Irrespective of how it enters the water, algae finds it hard to thrive if the pool chemistry is properly balanced.
If you have a green pool, it is a given that the pool’s pH levels are not within the recommended range.
A green pool can also be an indicator of a clogged filter. A change in weather can also introduce algae into a pool. Hence, it pays to be extra prudent during such a time.
Thankfully, green algae is the easiest to kill among all types of algae. Yellow (mustard algae) and black algae take a lot more elbow grease to get rid of.
Note: If you pool is dark green or if it has a blackish tinge, I recommend that you drain it completely and give all surfaces a good old fashioned scrub and an acid wash.
If you can see 6 inches below the water surface, chances are that the pool can be successfully treated with chemicals. So let’s begin:
- Balance Chlorine levels and pH: Test pH and Chlorine levels using a strip kit, liquid kit or any other pool testing kit of your choice. The pH should be between 7.2 to 7.6. If it is high, you have to lower it by adding muriatic acid and if it is too low, it can be increased by adding sodium bicarbonate. We have detailed info on how to lower or increase pool pH. Please feel free to read, learn and execute.
- A green pool means that Chlorine levels are probably below normal. Test and adjust the chlorine level. This is also done with the help of commercially available kits. These are not very expensive and easier to use than you might think. Do not be intimidated by them even if Chemistry is not your strongest point. The instructions on the kits are pretty straightforward. Follow them and you will be fine.
- Now that you have taken care of some basic parameters, it is time to shock the pool. Shocking means altering the pool chemistry in such a manner that it becomes highly unconducive to the growth of bacteria, algae etc. This change in chemistry is induced for a short time and the water is then rebalanced.
- It is highly recommended that you use a calcium hypochlorite pool shocking product. You’ll have to determine the dose for your pool size by reading the instructions on the packet. Each product is unique but according to science, pool water needs to be chlorinated to 30 parts per million in order to destroy algae completely.
- Pro tip: Throw cleaning equipment into the shallow end of the pool while shocking; it sanitizes the equipment.
- Once you’re done with shocking, it is advisable to run the filter for at least 6-8 hours or more if required. You may need to backwash the filter as this helps to reduce pressure and increases the flow rate. Use a long pole brush to scrub the pool surfaces as the water is being filtered.
- Even after filtration, you might notice that the water is cloudy. This is because of the residual bacteria and dirt particles that are small enough to pass through the filter. A flocculant can help to take care of this cloudiness. Floc basically binds to algae and other dirt so that it clumps together and is easy to vacuum or filter out.
- If you followed all of the above steps well, you probably have a crystal clear swimming pool. But wait, it’s not ready to jump into yet. Do NOT let anybody enter the water before testing pH and chlorine.
- Once you’ve determined that the water chemistry is right, the pool is ready for you to enjoy. I recommend adding algaecide as it kills the spores that somehow keep on finding various ways to enter the water. If you have a very mild case of pool algae, just adding algaecide can solve the problem. In most cases though, algaecide works best as a preventive measure.
Anybody who has dealt with a green pool knows how tiring the entire process can be. Cleaning the pool on a regular basis and testing the water at least 1-2 times a week can help prevent re-occurrences of algae.
A good robotic pool cleaner helps to keep a pool free of algae, dirt and other debris. Most people totally suck at cleaning the pool manually. However, as premium robotic pool cleaners can be pre-programmed to clean at the designated intervals, you don’t even have to think about cleaning the pool. Just set it and forget it!
