From Green to Clean


You’ve been living for the weekend; you have friends coming over later, to just escape life for a moment and enjoy the coolness in this Florida heat, ONLY TO FIND the pool is as green as your neighbor’s fake lawn. It may not be as bad as it looks.

How did the Algae get in my pool in the first place?


Algae is a one-celled plant that is the big scary monster pool owners are frightened to death of. (I’m writing a Horror film on Pool algae coming soon.) But how did it get there??? The first thought is, well it needs chlorine, so we blame our spouse for not stopping by and grabbing chemicals on the way home or call the pool guy and unload the last four weeks of stress on him. However is it is a bad as it looks? Am I going to keep asking questions or am I going to answer myself? HMMM? Well, here we go.


Pool water readily contains everything algae needs to grow, carbon, hydrogen, oxygen, nitrogen, and phosphorous. Some major contributing factors out of our control are sunlight, temperature, humidity, floating debris and pollens.  And factors we can control such as filtration, circulation, flow, sufficient levels of disinfectants, these are all things we can take control of. Don’t be too hard on yourself because, at the end of the day, pools are prime real estate for algae growth.

DID YOU KNOW: Contrary to popular belief, algae in most cases is not harmful to users.



Millions of algae spores are carried every day into our pool and spas. Some algae have the ability to reproduce very rapidly if the conditions are favorable, turning a clear pool green in less than a day. That is coming directly from NSPF POOL AND SPA OPERATOR HANDBOOK so that you don’t think I’m making it up. The best way to get algae out of your pool is never to let it get in. There are many factors to keeping a pool properly functioning and chemically treated to keep algae out. Make sure to have:

  1. Good filtration
  2. Good circulation
  3. plenty of running time 8 hours minimum recommended in summer months
  4. Routine super chlorination
  5. Algaecides and algae prevention treatments
  6. Brushing
  7. Phosphate remover
  8. Keeping all other chemicals balanced (PH, TA, CYA, etc.. )
  9. Optimism and a good attitude

How do I remove it?

PicsArt-300x167The algae are in the pool now how do I get it out? It’s honestly not too hard just requires a lot of chemicals ( can be expensive) and minimal equipment. Test all your levels and find where the problem is in the chemistry. ( HINT: if your chlorine is high and your pool is very green, your pool very well may be over stabilized, and the water may need to be diluted) . But find the dilemma in the chemistry and don’t forget to check the phosphates.  Also :

  1. Super-chlorinate 10 PPM plus
  2. Balance all other chemicals ( Balance according to labels on any algaecides or green pool treat)
  3. Brush down entire pool  all walls, floors, steps, nooks and crannies algae can hide
  4. Make sure pool has plenty of Circulation
  5. Make sure filter is clean
  6. Add Algaecide, phosphate remover, clarifier (optional and can help, be careful-many algaecides eat away at your chlorine)
  7. Run filter 24 hours
  8. Repeat as much as needed.


Algae can easily get in pools, but truth be told it can easily be removed as well. It’s not a matter of if but when are algae going to attack your pool. Some summers are worse than others but just be ready and be optimistic because now you know how to take care of it and defend yourself and the pool.
