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. Even a wire brush won't remove it. It's driving me nuts, and despite being clean, no one wants to go swimming. Any ideas?

Buy generic bleach. Not ultra or scented. Just plain old bleach. Pour in 3 gallons/5000 gal of pool water with the filter on overnight. The next morning you will be amazed how clear the water is. Cheap and effective. (03/14/2006)

If you pool has a liner, be careful with the bleach, if it is cement, bleach, bleach, bleach and stay out of the pool for several days. (03/14/2006)
Buy some algaecide, whatever kind is recommended for your type of pool. Bleach won't work, chlorine won't work. you have to buy something specifically for killing algae. (03/14/2006)
Have your water tested by a pool company. Most of them will do this for free if you will be buying chemicals from them, otherwise there may be a fee of around $10. If the chemical balance is not correct you can dump in as much chlorine as you want and it will have absolutely no effect. (03/15/2006)
The algacide will help, but, also, add a couple of boxes of baking soda to the circulator. This seemed to help me with mine. Good luck. Patsy (03/15/2006)
If the algae has stained the pool, you will need to have it acid washed to remove the stain. (03/16/2006)
I used to work for a pool store. Go to a reputable pool company and bring a current water sample from about 12 inches from the surface. Have them test this for pH and acidity, chlorine levels, etc. Use the algaecide they recommend and kill this stuff. Adjusting your pH and acidity without doing this first is a waste of time and money as the algae causes these to go out of whack. Keep circulating your pool and keep brushing the spots. This can take a lot of time. Once it is clear, maintain your pool. This is what caused this problem to begin with. Don't be afraid to ask questions. These people know what to do to help your pool.
