Hot weather makes a swimming pool a fabulous addition to your backyard, making you the envy of all your friends and family.  It can also make your pool turn green overnight.  Left on its own, the shade of green you end up having to deal with can vary from emerald to dark forest.

And, while it won’t be possible to achieve an overnight fix, with some time and effort and the right tools and chemicals, it is possible to bring it back to that cooling shade of clear blue you want.

Here’s how.

Get Rid of Any Large Pieces of Trash

Using a large net (a hand skimmer isn’t going to cut it), remove as much foreign material from the pool water as possible.

This must be done by hand, especially if you can’t see the surface of the bottom.  All those excess leaves, branches and insect bodies (ick) will very quickly clog up your skimmer and filtration system if you try to use a pool vacuum.

Of course, this will also stir up the smaller sediment that has settled to the bottom, but that will resettle in approx. 24 hours.

Reset the PH and Alkalinity

If you don’t have one already, get a pool testing kit from your local pool supply or DIY store.  The kit should have instructions on how to test your pool water and then let you know what you need to bring it back to optimum PH levels.

Or, take a fresh water sample to your local pool supply store.  Many of the major chains provide a free testing service and will then be able to advise you on the proper chemicals and amounts you need.

Get Shocking

Shocking your pool equals adding high amounts of chlorine to the water.  This kills off the algae and bacteria breeding in the water.  Depending on how long your pool has gone without treatment, it may take several treatments over multiple days to accomplish this.

To start, add 3 or 4 gallons of liquid shock. If you see little or no results overnight, do this again. Fortunately, it’s not possible to over shock a pool.  You will need to keep up this routine until the water changes color to light green, cloudy white, or clear.

NOTE:  the more you add at a time, the faster it will work.  If your water is a really dark green, increase the amount you are using in one treatment.

Shock is also available in powdered form but liquid works much faster, so if you are dealing with a really big job, stick to liquid.

If you are not seeing results very quickly, consider using an algaecide as well.  Your local pool supply store will be able to advise you on the best type for your area.

Filter – Filter – and Filter Again

If you have a filter system put on a timer, you’ll want to turn it off or bypass it for a while.

For best results, keep your filter going 24 hours a day.  Of course, with all the stuff you have to remove, you’ll need to backwash it’s a lot more.  If you have the time, you’ll get the quickest results by doing this at least four times each day.

Also, if your system includes a D.E. filter, make sure to add more D.E. after each backwashing.

Still Green?

After five days of this routine, if you still have a sick looking pool, check your filter.  More than likely, it’s not working the way it should.

If you think this may be the case, you’ll need to have it check out by a professional.

Once the Green Is Gone

If you have gotten to this point, congratulate yourself, you’ve accomplished a huge task.

At this point, there should only be some small debris on the bottom.  This can be cleared using your pool vacuum.

NOTE: if you appear to have more debris than is recommended for your vacuum, it would be best to have a professional come in to perform a power vac. This will avoid putting too much wear and tear on your own vacuum and help it work longer.

Keeping it Clear

Now that your revived your pool to its full glory, make sure you have what you need to keep it that way.  This means shocking at least once a week or more depending on the weather.  Other items to keep on hand are:

  • Algaecide
  • Backwash Hoses
  • Chlorine Tablets
  • E. Powder
  • Hand Skimmer
  • PH Balance Kit and Chemicals
  • Vacuuming Equipment

Keeping up a consistent maintenance routine on your pool every week will help ensure you won’t have to go through this trouble again.

If you are planning to be out of town for more than a week, consider finding someone to keep up the maintenance for you.  The added expense up front will save you days of trouble and extra chemicals later.
