How To Easily Clear Up Green Pools In 5 Days

Green pools and cloudy pool water is normally a lack of pool chlorine. You can easily clear up a green swimming pool.

How To Clear Up Green Pools

Green pool water is the bane of every pool owner's existence.  It comes on when you least expect it and, like an unwanted relative, seems to hang around forever. But there is a way out.  You will first need to have a complete list of chemical readings.  You can get this done at your local pool store or use a good pool test kit yourself. I'd encourage you to get a Taylor FAS-DPD K-2006 pool test kit.

You MUST have the most current and accurate readings possible in order to clear up your pool.  If you don't it's nothing more than a guessing game.  Never rely on anyone who simply hears of a green pool then tells you how to clear it up without knowing the chemical readings, your pool size, and filter type. 

Word Of Caution  

If anyone says to you, "Oh, your pool is green?  Let me tell you how to clear it up.  First, get the pH and alkalinity in line.  Then shock the pool and add a clarifier.  If that doesn't work, put 2 tabs in the skimmer and add a couple bottles of phosphate remover and circulate the water for 24 hours.  If that doesn't work, add 2 bottles of algaecide, 3 more bottles of phosphate remover, and put another tab in the skimmer."  Does that sound familiar?  It just might.

Folks, I've been doing this pool gig since 1999.  I've cleared up over 700 pools in 3 different states (Arizona, Oregon, and Florida).  All were in different locations, different cities, different temperatures and climates with different water sources.  I absolutely guarantee that advice will cost you hundreds of dollars, countless hours, and your Summer will be ruined.  It's virtually impossible to clear it up without the right information and the proper understanding of pool chemistry that applies equally to every chlorine and salt pool in the world. 

Are you sick and tired of fighting your green pool?  Too many chemicals?  Too many trips to the pool store?

In my exclusive 12 Part F.T.A. Video Series I show you how to not only clear up your pool but how to keep it perfect all swimming season.

Your Pool Chemical Readings

Don't rely on test (guess) strips.  They're easy and convenient but won't give you the actual numbers you need.  The colors "Red" or "Orange" are not pool chemical readings.

How To Clear Up Green Pools

 Your pool chemical readings are:

  • Chlorine (Free Available & Total Chlorine)
  • CYA (cyanuric acid/stabilizer)
  • pH
  • Total Alkalinity (TA)
  • Calcium Hardness (CH)
  • Metals (iron and copper)

There are endless reasons why pools go green or cloudy.  Chemistry. Filtration.  Lack of chlorine.  Bad or inconsistent chlorination.  The list is long and complex. 

Warning About Your Pool Liner

You may have read or heard that if you have green pool water you need to doubletriple, or even quadruple shock your pool, depending upon how "green it is".  This is patently and across-the-board false.  By bringing your chlorine level up to 30 ppm, 40 ppm, 50 ppm or higher, you run the chance of bleaching the liner out.  Maybe not the entire liner, but you could have chemical stains, and chemical stains CANNOT be removed off a vinyl liner.  Hopefully you'll watch the below videos.  The water was absolutely filthy and solid green with water bugs, debris, and mosquito larvae.  I didn't "quadruple" shock the pool.   I employed the right techniques and used easy 1st Grade Level Universal Laws of Pool Chemistry & Physics and my F.T.A. Process to clear it up.  There is absolutely no reason to increase your chlorine level to such a dangerous level.

It's also good to know the readings for your fill water as well.  You want to know what's going in your pool at all times.  Next is to minimize the clarifier, flocs, and/or phosphate remover use.  "Why is my pool cloudy?"  This might be one of the reasons.  Remember when you have green pool water, shocking a pool is a process, not a product.  Regardless of what anyone has told you, this is the truth.  There are no products that are "shock".   The package might be labeled as "shock", but it's misdirection on their part.

Green Pools & Pool Chemistry 

  • Reduce the pH.  Chlorine works better at a slightly lower pH when you have green pool water.
  • Be sure the total alkalinity is between 80 - 120 ppm
  • Add the chlorine in the evening then retest in the morning (before the sun has a chance to hit the pool) and see how much the level has dropped. If it drops more than 2 ppm, you still have an algae problem. Make another adjustment.
  • Sweep the sides and bottom to break up any hot spots. Keep the filter running 24/7.
  • Add enough chlorine to increase your chlorine level up to 15 - 20 ppm when your pool water is green.  Retest the chlorine and CYA in the morning.  You'll see how much chlorine has been used through the night.  Chlorine is used to sanitize, oxidize, and kill organic matter in the pool.

During this process you can use a PolyQuat 60 algaecide as an added backup against any algae blooms that might occur.  The trick in clearing up a green swimming pool is to get the pH in line and maintain a high chlorine level for a period of time. That's why you shock in the evening, retest in the morning, then add more chlorine.  Let the filter do its job. Be sure to clean the filters or back wash every day.

Remember to test morning and evening and keep the chlorine level at 15 ppm or above as best you can.  You may need to do this for a few days.  When the pool turns a white/gray color, you only lose 1 - 2 ppm of chlorine through the night, and you're water is clear, you'll know the algae is dead.  If the chlorine loss is more you probably still have some residual algae.  If you have a pool store that's close, take a sample of water to be tested after every turnover of the water.  This is normally about 8 hours.  Morning and night.  They should do it for free.

Make sure the CYA is in the proper range of 30 - 50 ppm.  Add stabilizer if it's low.  To quickly increase your CYA you can use:

  • Dichlor
  • Trichlor
  • Liquid or granular CYA

Follow the direction on the package.  Be careful when using Dichlor as it can get out of hand quickly.  For every 10 ppm of chlorine added with Dichlor, you'll raise the CYA by 9 ppm.  For every 10 ppm of chlorine added with Trichlor you'll raise the CYA by 6 ppm.  Use liquid chlorine when shocking a pool.  Chlorine granules have a pH of 12.  Your pH level might go through the roof and you'll be adding more calcium to your pool.  To help with the filtration at the very end you can use a clarifier.
