What Causes a Green Above Ground Pool And How To Clean It

A green above ground pool is never a pleasant sight. Not many of you will disagree with us if we say that a pool, especially the in-ground ones, are just a costly embellishment to our house. Having a swimming pool in front of the house or the backyard is not necessary. Neither is basic. Still, people fulfill their desire of having a swimming pool through, at least with the comparatively small, affordable, and feasible above ground swimming pool.

Above Ground Pool

Yes, those who do not have a permanent resident and need to move from one place to another frequently opt for above ground pools. Of course, they are less costly, and you can uninstall them and re-install them to the new site you just moved in.

However, this doesn’t change the fact that it remains a swimming pool, and you use it the same as a regular costly swimming pool. It will turn green, and you will have to clean it the way the owner of an in-ground swimming pool does. Therefore, here we are telling you how to clean a green above ground pool, step by step. But prior to that, let’s look at what causes the green in an above ground swimming pool. You know the cure only after assessing the cause.

What Causes Green Above Ground Pool

The main reason for a green above ground pool is none other than the growth of algae in the water. Algae is already there in the water. You just need to give it a slight scope to expand. Now there is no one single reason for the algae to grow in there. So, we are going to provide you with the main three.

1. Unused Pool

If you have left your above ground pool unused for days, and there is no activity in the water, resulting in standstill pool water, algae are bound to grow. It doesn’t take much time for algae to grow and spread all over the pool. So, almost within a day, the whole pool turns green, especially when it’s an above ground pool that is already small in structure.

2. Low Chlorine Level

Maintaining a certain chlorine level in the pool water is a must for any swimming pool. So, an above ground pool is no different. Chlorine is fatal for the algae and the created bacteria and germ due to it. The chlorine level of the above ground pool should be something between 2.0 to 4.0 parts per million. So, when the chlorine level goes off-balance, algae grows and grows faster. Therefore, a green pool.

3. High pH Level

Even a high pH level causes a sudden bloom of algae. The low chlorine tends to higher the pH level and vice versa. High pH level means the water is acidic, and there is no balance in the chlorine level. Thus algae gets the scope to grow.

Too much cyan uric acid in the water and excess amount of UV rays also causes a green pool. So, all in all, if you can remove the algae from your above ground pool, you can solve the green water issue.

How to Clean a Green Above Ground Pool

Follow the below instructions for cleaning your green above ground pool.

Step 1: Collect the Tools and Chemicals

To clean the green pool, you will need a few tools and products. The moment you have purchased an above ground pool, buy these essentials, and consider all as a package. You will need a brush to scrub the surface, pool shock or chlorine tablets to shock the pool, an above ground pool cleaner or a leaf rake skimmer with a telescopic pole will do to remove the dead leaves and branches, test strips to test the pH level, clarifier to clear the cloudy water and perhaps a few more.

Step 2: Remove the Leaves

With the skimmer pole or leaf net, remove all the dead leaves from the pool water. Not just the fallen leaves, branches, large particles of dirt, all should be skimmed from the pool water. Do not forget to take out the leaves and pebbles from the bottom of the pool too. You can also use a skimmer with finer mesh to skim the smaller particles.

Step 3: Check The pH level

After removing the leaves and dirt particles, time to check the pH level. Use the test strips, and if the result is something, between 7.2 to 7.8, you are ready to take the next step. If it’s higher, add sodium bisulfate to lower the pH, and if the pH is low, then add baking soda or soda ash. The pH will rise.

Step 4: Shock the Pool

The amount of pool shock you will need depends on the quantity of water in the pool. One packet of pool shocks that are readily available in the market can treat 10000 gallons of water. So, mix the right amount of pool shock in a bucket of water and then pour the mixture in your pool. Doing it at night and leaving it overnight will provide better results. Run the above ground pump overnight. Water in the pool must circulate continuously.

Step 5: Brush the Sides

You can do it right after pouring the chlorine mix, or you can brush the surface of the above ground pool thoroughly and then shock the pool. It’s up to your convenience.

Step 6: Run the Pump

After you have shocked the pool, you must run the pool pump for a day to reuse it. If the water gets cloudy, which happens in most cases, throw any pool purifier, run the pump continuously for 24 hours, and both the green and foam will vanish. Using the right amount of chemicals is necessary to balance the pH, chlorine, and alkaline levels of the pool water.

If the above ground pool is for adorning the house, it should look good. And a green pool is not what looks good. Moreover, you are dunking your whole body in there. Who in his right mind will prefer doing that in green water full of algae! So, always make sure to circulate your pool water to avoid the water from turning green. And if still, your pool water turned green, you know all the steps.
