How do you treat black algae in pool?

Answer 1

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

Answer 4

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.

Answer 5

Algecide Gel

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.

Answer 6

I would take some bleach and a rag or course sponge and rub it right out or use a pot scrubber nylon pad.
