Wondering How To Treat A Green Algae Pool?

It’s the first holiday weekend of the summer of 2017.  If you are lucky enough to have a swimming pool in your backyard, hopefully, you enjoyed swimming in your pool this weekend.

If your pool wasn’t clear and you were fighting algae, then the purpose of this post is to share with you exactly how to treat the dreaded algae that will show up in your pool from time to time.

WHAT CAUSES ALGAE?

Algae is caused by the chlorine levels falling below acceptable levels.    An acceptable level in a residential swimming pool is between 2.5 to 5.0.   At an acceptable level, the chlorine can properly clean and sanitize the swimming pool.

Chlorine levels can be lower or higher.   If they are lower in the heat of the summer and spring, then you run the risk of an algae bloom.

And, there isn’t a reason to have your chlorine levels consistently above 5.0 unless there is always a high bather load.

You need to have your chlorine at higher levels when the pool has algae.  You need to have the algae at those higher levels in order to kill the algae.   But, it is not necessary to keep those high levels on a regular basis.

HOW DO I REMOVE THE ALGAE?

Algae can sometimes be removed by throwing some shock on it.  But once it has attached itself to the walls of your pool, then shock alone will not remove it.   You need to use an algaecide.

Choosing an algaecide that works right for the algae that you are seeking to remove is the first step.   If you have yellow algae, then you use an algaecide that is specifically tailored to treat the algae.   If you have darker algae like green or brown, then algae that treat the yellow kind is not best to remove the algae.

There are many good algaecides on the market.  If you take care of your pool, then go to your local pool store and request a recommendation.   If someone takes care of your pool, then they should know the best one to treat your pool.

With the right algae, you can get the pool cleaned up and treated in a matter of days.

So, after treating the pool with an algaecide, your next step is to shock the pool,     Shocking the pool alone will not kill algae once it has turned green.

SHOCK THE POOL

The next step is to shock the pool.  Once the algae have taken hold of the walls, you need to get the chlorine levels raised high.   You broadcast the shock throughout the pool.   The next step is to brush all the walls of the pool.  Just doing a quick brush will not sufficiently treat the algae.  Giving the walls of the entire pool will remove the dead algae and have it settle on the bottom of the pool.

By the time that you leave the pool, it may have actually started turning.   But, likely it will still be green and cloudy.

Next, come back and vacuum up the dead algae.  It is best if you do a system vacuum.  That way you are removing the dead algae and hot having it pass through the filter or the pool equipment.   We usually wait a day or two in order to make sure that everything has settled to the bottom of the pool.  You want to make sure that you don’t do a vacuum that would stir up the dead algae.   You want to remove the dead algae.

Now that the pool chemicals are improving.  Make sure that come back and balance out the chemicals.   They will eventually return to normal levels.

The key to preventing the algae from coming back is always keeping the chemicals maintained.
