Scrub all the infected areas with a chlorine tablet. (you will probably want to wear gloves for this step.) now that you’ve brushed away the protective pool surfaces of the algae, the chlorine can penetrate it and get to the roots. break one in half and use the rough side to scrape the algae. 5. Wash your bathing suits in a washing machine and dry them in your dryer. wipe down everything you removed with a 50 50 solution of bleach and water. you can use a scrub brush for a more thorough cleaning. place your pool cleaning equipment (telescopic pole, net, brush) in the pool so that it becomes sanitized. 3.
However, the pool needs some pre treatment, which will also help stop the black algae from coming back. first, clean the pool filter. remove it and leave it to soak in a 50 50 solution of water. Scrub the pool thoroughly, and a second time with the steel brush if necessary. small black spots on the floor or the walls can be removed with a targeted application of chlorine granulation. break a chlorine tablet and rub the black algae with the edge. wear gloves or use a holder for the tablet. 4. scrub the black algae spots. use a putty knife, a pumice stone, or a hand held wire brush to get all the spots you couldn’t get with the big brush. you can even use a chlorine tablet because not only does it have a scrubbing surface, but the chlorine gets applied chlorine directly to the bacteria. Step 2: test and balance pool water chemistry. before tackling black algae, ensure your pool water chemistry is balanced. test total alkalinity (ta) and ph levels, aiming for 80–120 ppm for ta and 7.2–7.4 for ph. to make your pool water testing process accurate and simple i recommend using the ultimate pool water tester.
