how do I clear my pool water of green algae?

Question

pool water is green
Added a gallon of acid yesterday and cleaned off the walls

Answer 1

You need to add algeside to your pool, and vacumn it often.

PROBLEM: Green Floating Algae

ANALYSIS:
Algae growth is usually caused by one of the following conditions:

Inadequate Free Available Chlorine Levels. Free available chlorine levels can be depleted quickly by heavy rains, high bather loads or poor maintenance procedures. During such conditions, check free available chlorine levels frequently and add an AquaChem sanitizer as needed, according to label instructions.
High pH. Alkaline water prevents chlorine from effectively killing algae. AquaChem pH Decreaser used as directed on the label will lower pH to the correct level of 7.2-7.6.
Dirty Pool Surfaces. Dirt and slime accumulation on pool surfaces provides the perfect location for algae problems to start. Weekly brushing and vacuuming eliminate this source of trouble.
SOLUTION: AquaChem Algaecide Plus or Black Out

Check filtration and circulation systems for malfunctions.
Check the pH and adjust (if necessary) to 7.2 — 7.6.
Following label directions, add AquaChem Algaecide Plus (for all pool types) or Black Out (for white plaster pools).
Allow algaecide to work overnight. Then brush and vacuum pool surfaces. Backwash the filter to remove accumulations of dead algae and debris.
For major infestations, a second treatment may be needed.
Return to normal maintenance with AquaChem sanitizers, shock products and balancers.
As an algae preventative, add AquaChem Algaecide Plus or Algaecide Concentrate 60% per label directions as listed for preventative maintenance.

Answer 2

If you already have algae in your pool, then you will have to add both a biocide and pool shock. Your local pool supplier can provide both or you can go Home Depot or Walmart. You will use much larger amounts of pool shock than you normally do. If for instance your pool is 20,000 gallons, you will probably add 10 pounds of pool shock along with the biocide. Be sure to throw all your pool tools and toys into the water as well, because they will be contaminated with the algae bacteria.

Then run your pool filter until the system clears. You will have to brush the side and bottom to be sure to get all the algae killed.

Once your pool has cleared, you will then need to backwash the filters to clear out the algae filtrate.

In the future keep your chlorine level high....at least 5 ppm. I keep mine close to 10 ppm all the time. And don't worry....it's not chlorine that makes yours eyes get irritated. It's pH of the pool water that stings your eyes.

Ask your pool supply place to help you understand the chemistry and you'll enjoy your pool a lot more.

Your going to need to shock the crap out of it. Have your PH tested a;so. Algae can seem to grow over night especially after a lot of rain and wind. Carries pollen and such into the water. Super chlorinate the water before closing up and covering for winter. I would recommend clearing it up before you cover it for winter. You can buy winterizing kits for your pool size and a good cover. The colder the water gets the harder it is to clear up. Yes the algae can stain your liner and the chemicals can do damage as well. You should get about 8-10 seasons out of a good liner.. If you close it up clear and cover it with a winter cover, dark, lets in no light it will be clear when you open it up next season.
