Finding Black algae in the pool is bad news for any pool owner. This stuff needs to be handled as quickly as possible, because if you wait it will turn into a major disaster. Getting rid of Black algae requires some hard work because it has a waxy coating that protects it against chlorine and algaecide. There is no easy way to get rid of black algae. It will take manual work , the right chemicals and vacuuming to eliminate this stuff To handle black algae spots you will need: a stiff pool brush, chlorine tablets and algaecide. These directions are not for a vinyl-lined pool. Do not swim in your pool during the black algae spot treatment. Shutting of the pool pump will help in preventing the further spread of the Algae during treatment, Each black algae spot needs to be brushed with a stiff brush in order to break the protective waxy surface. Use a chlorine tablet spot treats the black algae spot (not on vinyl lined pools). Then pour concentrated all-purpose algaecide on the spots Leave the dissolved algaecide and chlorine on the black algae spot over night. If you would rather use chlorine granules just get some old socks to put it in and place it on the spots instead On the following day loosen the dead algae spots and vacuum to waste. Do not put it through your filter, as there is no guarantee you killed all of it. Repeat the procedure for any further spots you see it because you need to stay on top of this stuff if you have been blessed with it. If there are still some black algae spots you should repeat the process. After vacuuming to waste set to rinse, rinse for a minute or so and then to filter start filter pump for circulation. Adjust pH. And keep the chlorine level adjusted to 7.2 - 7.6) to prevent it from happening again. Keep your chlorine residual at 1.0-3.0ppm.
I had to drain the pool, use a power washer and lots of chlorine. Then had to shock the pool at least twice before it started staying clear. It's a lot of work and I would reccommend using a pool service to monitor chemical levels in the pool, that way if you get the black algae again, they can do all the work.
had the same problem . if you have a liner and it is on the underside of the liner what i did was take a block of cloriene and put it in a sock and put the sock on top of the black mold. let it sit for a few days then remove
Black algae is a pain!!! I would recommend putting in 2 gallons of ammonia and a tri-chlor shock treatment for your size pool with a gallon of muratic acid. run pool for 24 hours and if you can get your hands on a 50 lb. bag of Borax, put entire bag in followed by 3 gallons of acid the following day. Then wait 2 days before swimming and adjust PH using acid every week. OH!, and brush algae spots and entire pool with a all steel wire brush after ammonia treatment.

You'll have to empty the pool. Scrub and clean the pool and make sure the sand filter is up to par. Then, refill the pool and use the proper chemicals. In my subdivision, an inexperienced pool guy managed the chemicals badly during hot weather. Make sure you are using the proper methods and you won't get black algae again.
Be careful about emptying the pool. Floating a fiberglass pool is a common issue and will do a lot of damage.
I would take some bleach and a rag or course sponge and rub it right out or use a pot scrubber nylon pad.

Is draining a pool an option for treating black algae After two weeks of rainy weather and no chemical treatments our in ground pool is consumed with black algae. It is pitch black from the surface?
Black algae is the hardest to get rid of However be very carefull when it comes to emtying your pool especialy after rain as the ground water around your pool could forse it to start floating. which would ruin your pool altogether. Let me tell you this - in 2 weeks you could not get that much black algae. It took you months of neglect to harvest this crop of algae. I think you pool plaster could be no worse than as if you left the pool dry for the entire summer. If th estatement above thinks that emptying the pool during rainy weather is going to be bad for your pool ( and it will) then what you have spurned here is just as serious. Take some lessons on how to maintain a pool and look for a pool contractor who can remove all the plaster in your pool and start over again. Black algae is not your only problem. As an inexperienced person with a pool you can not see the problems that have developed along with the black algae. Tsk, tsk, tsk, tsk. Shame on you.

Will power-washing remove Black Algae from a Gunite pool?
Probably not. Since "Black algae" has a crusty layer over it you will need to use something abrasive to break open the spores. Get a product that says "for black algae" We usually increase the chlorine levels too (if no one is using the pool)
After two weeks of rainy weather and no chemical treatments the in ground pool is consumed with black algae literally pitch black from the surface For ease of treatment should we drain the pool?

Can you get sick from black algae in pool?
yes you will get sick or you may even die
When you vacuum the pool the algae returns the next day how come?
Vacuuming just moves the visible algae to the filter. It does not kill it. You need to shock the pool and treat with algaecide. Brush pool thoroughly and vacuum up dead algae. Then clean your filters. It may take more than one treatment to kill all the algae. Also have your pool tested for phosphates. Phosphates are basically food for algae. If algae has a good food source, it can survive in even high amounts of chlorine. Therefore, you may also need to treat for phosphates. It would be best to take a water sample to a retail pool store such as Leslie's. They will give you printout of what your pool needs, amounts or chemicals, and order to apply them.
