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.
What do you do if you have clusters of black dots on the surface and bottom of your swimming pool?
That is probably black algae. You need to go to a pool store and have them advise the proper chemical and use of that chemical for your pool. It may take a granular product for white plaster pools. Color tinted pools are another matter and you should use a liquid black algae treatment. And if you have a vinyl liner pool I just do not see how in the world you could get black algae. Black algae comes from not maintaining proper chlorine levels and adjusting the pH.
