On The Fine Living Channel there's a show called "I want That!" & they showed a solar pool cleaner... it floats around in your pool & uses the solar radiation to run a battery that does something to clean the algae, etc. You're supposed to need far less chlorine. Go to the Fine Living Channel & research the show's info or Google "Solar Pool Cleaners" The one I saw sold for around $75 bucks. Not bad if you use less chemicals!

It is hard to clean, use plain old household bleach, try added a pint of bleach to pool water everyday to keep it from happen a gain. To get rid of the algae what there now, drain the pool, and spray with pure bleach. let it dry then repeat, if you scrub the put do so, you can add a little comet to the spot also.


I had this in my pool last year, and it really took me along time to get that stuff out. This year i just put a pint of bleach in the pool, and I did not have any algae this year.

Green Algae, amongst the other forms of algae is mostly stimulated by the acid water state of your swimming pool. However, there are solutions which do not require you putting chemicals in the water, hence also reducing the impact those have on your health. you can do this by changing the constitution of the water, from acidic to alkaline, using a water ionizer such as the one at: for example.


This will result in less costs, less maintenance, and a healthier swimming environment you can actually enjoy!

There are several guides on how to clean algae but here is a simple way to take care of your problem:

  • Algae is caused by low levels of chlorine in the pool water. So you'll need to shock the algae with a high level of chlorine. You can normally correct this condition within 1 to 3 days, but it can take up to a week if your pool is bad. Pour the chlorine in the pool.

  • Now use the pool brush to scrub and clean the bottom and sides of the pool. The more algae you can remove with the brush, the less time it will take.
  • Test your pool's ph levels and add the necessary chemicals to the pool's water. You should wear safety gear when doing this and not breath in the pool chemicals.
  • Continue to use the extra large dose of chlorine shock in your pool and scrub the bottom and sides of the pool.
  • Test the PH balance of the water and adjust your chemicals.
  • Do this daily until the algae is gone in your pool.
  • Once the algae is gone you'll need to test the PH level of your pool and keep the pool chemically balanced so the algae doesn't return.

There are special chlorine-based algae cleaners for the pool. They shock the algae when they are brushed against the walls and floor of the pool.


You also need to test the waters PH and clean the water filter.

Cover the pool with an opaque cover when not in use. Algae can not grow in the absence of light. Salt will also discourage algae growth.

Filter systems in above-ground pools are often not as robust as in-ground pools. This can make algea growth more of a possibility. This is a page about algae in an above-ground swimming pool.

I have a pool, and it doesn't matter how much chlorine I dump in it, or how much I scrub it, the bottom is stained in places with a greenish algae-looking growth.
