Black Algae

I need suggestions on how to get rid of black algae. I live in southwest Florida and have your basic inground pool
Thanks

Suggestions:

• Get a K2006 kit.
• Read the Best Guess Chlorine page.
• Adjust your chlorine levels to the correct range for algae killing -- use the low end of that range.
• Keep the chlorine there . . . for weeks.
• Begin brushing REGULARLY.
• Do not wear high-fashion expensive swimwear in the pool. Skin is VERY chlorine resistant; women's swimwear that costs over $100 is NOT. Such suits are made to be seen in, not to be swum in. If you use the pool a LOT, all polyester water aerobics suits are super-durable.

Black algae penetrates down into the cracks and crannies of the pool surface. Even when it seems to be gone, it's not. If you keep brushing while maintaining chlorine levels, it will be *mostly* gone 2 weeks after you can't see it any more.

But, it will not be all gone, and will recur if you let chlorine levels go low.

Note that if you have stabilizer levels above 40 ppm, and do not READ and FOLLOW the Best Guess Chart, you're mostly wasting your time. Keep in mind that test strips are HORRENDOUSLY inaccurate when use to measure stabilizer.
