How to Clean a Green Above Ground Pool

Green pools are in vogue at the moment, but they can still be a pain to clean. Here’s your guide on how to get out of that pool with minimal hassle.

To clean a green above ground pool, you will need to use a sand filter. A sand filter is a type of filtration system that uses sand as the filtering medium. The sand filters clean the water by trapping large particles and then passing it through a series of small holes before releasing it into the pool.

Cleaning an Above-Ground Pool: A Step-by-Step Guide

Algae growth is rather prevalent in above-ground pools. Cleaning a green above-ground pool isn’t difficult, however it does need the following steps:

  • Time
  • Chemicals
  • Patience

Clean Up Your Above-Ground Pool of Junk and Debris

If you have algae in your pool, there is probably something in there that encourages it to develop.

  • Leaves that have died
  • Sticks
  • Bugs
  • Even just the knowledge that someone have been in your pool is enough to make you feel uneasy.

All of this indicates that the algae in your pool has something to consume. It’s your responsibility to get rid of that supper.

A decent pool skimmer will be required. Something with a long handle and a fine mesh is ideal.

Begin at the pool’s edge and work your way within. Empty the net on a regular basis to ensure that unclean water flows smoothly into the mesh and collects all particles.


The above-ground pool vacuum is another useful tool. This is ideal if the trash has sunk to the bottom of the pool and is no longer floating. The “vacuum” connects to your water hose and forces all particles into the netting.


When we had an above-ground pool, we depended heavily on this.

Check Your Above-Ground Pool’s Pump and Filter

Getting rid of all that junk and waste also helps to keep your filter clean and your pump from breaking down.

The two major elements that will get and keep your pool clean are your pump and filter. Your pump must be powerful enough to keep the water circulating at all times.

The filter must be clean in order to capture all of the pollutants that stimulate algae growth and turn your crystal clear pool sea green.

Your pool’s pump and filter are designed to keep it clean. Your pool will not remain clear for long if they are not operating.

Check the Chemistry of Your Green Pool

The pH of your pool should be between 7.2 and 7.8. Although this is greater than typical, the higher pH indicates that the shock therapy will be more successful. (More on it later.)

The next step is to check your Cyanuric Acid, or CYA. CYA levels should be in the range of 30-60ppm. CYA serves as a stabilizer for chlorine, allowing it to fulfill its function of eliminating algae. Maintaining stable CYA levels helps to reduce chlorine loss and improves the effectiveness of the chlorine.

The quantity of Chlorine that isn’t bound in your pool is the final chemical to examine. The quantity of chlorine that has not been mixed with the previously chlorinated water is known as Chlorine that isn’t bound. That implies it’s completely free to use as a pool sanitizer.

Before you start cleaning your pool, make sure these chemical levels are correct so that the next stages are more effective and save you time and work.

To keep your pool’s sparkling clear water, keep an eye on these three chemical levels after it’s been cleaned.

Get Rid of the Algae in Your Green Pool

When cleaning your above-ground pool, this is the most crucial step. When you “shock” your pool water, a huge volume of chlorine is added to eliminate any algae while also sanitizing it.

You should carefully consider the kind and quantity of chlorine you will need. The amount of chlorine you’ll require is mostly determined by the size of your pool. In general, the shock should include a minimum of 70% chlorine. You’ll want to buy enough shock to repeat the procedure two or three times.

Consider purchasing high-quality shock from a business specializing in pool supplies and equipment. While it may be tempting to hunt for shock at an ordinary retail shop such as Lowes or Walmart, the chemicals offered there are sometimes out of date. Keep in mind that you’ll probably need a lot of chemical. Furthermore, you want the chemical to get the job done correctly the first time. You will be able to enjoy your pool sooner if you use a higher-quality chemical.

There are two other things to think about:

  • Non-chlorine shock is used by certain persons. While this is good for keeping your pool clean, you’ll need the real deal to fully clean your above-ground pool.
  • Consider using an algaecide if your pool is quite green. This kills the algae in combination with the chlorine.

Start the pump in your pool.

Now that your pool has been cleaned and the shock has been applied, the following step is to put all of those chemicals to work. They must move and circulate in order to do this.

  • Run the pump for twelve hours after adding the first round of chlorine.
  • Clean out any dead algae or other debris that has accumulated to the bottom of your pool using a vacuum.
  • Run the pump for another twelve hours after adding the second round of shock.
  • Make sure your filters and pump are in good working order.
  • Brush behind ladders and in areas where the algae has clumped together using a brush.
  • Continue to operate the pump for another 24 hours after adding the last round of shock.

Keep in mind that your green above-ground pool will not be sparkling clear right away after you clean it. Your pool’s water will gradually turn from green to cloudy. But don’t be concerned! The procedure is operating if the stage is overcast. Continue to operate your pump until the water is completely clean. After you’ve completed the full shock procedure, remember to remain out of the water for 24 hours.

What Makes Your Above-Ground Pool Green?

It’s easy to figure out why your above-ground pool is a wonderful emerald green. Your green pool is teeming with life. Algae is the name for these organisms.

A few things are required for algae to thrive. If you have those five items in your above-ground pool, you will have a vast swimming pool full with vivid, healthy algae. The greener your pool is, the more algae are attracted to it and invite their pals to dwell there as well.

In order for an algal bloom to flourish, it must have the following ingredients:

  • Still water: For whatever reason, your pool pump may not have been operating.
  • Warmth: Summertime and hot weather are linked with swimming pools.
  • Algae may develop even if you take a brief vacation.

The Steps You Must Take Over and Over to Keep Your Pool From Turning Green

You must not only learn how to clean a green above-ground pool, but you must also learn how to keep your above-ground pool from going green again. Fortunately, those steps are simple, but you must follow them consistently.

The procedures for keeping your pool fresh and clean are quite similar to those for keeping your green above ground pool clean, but with less chemicals.

  • Check your chemical levels on a regular basis:
  • pH
  • CYA
  • Chlorine that isn’t bound
  • Cleaning your pool on a regular basis (daily is recommended) will keep debris out.
  • Check your filters on a regular basis.
  • Make as much use of your pump as feasible. When the weather is nice and you use the pool often, some people recommend leaving it running throughout the day and turning it off solely at night.

Changing from a green above-ground pool to a clean one

If you follow these measures on a regular basis, you may prolong the life of your above-ground pool. You will be able to enjoy your clear, clean above ground pool every day of the summer after you understand how to clean your green above ground pool.
