Look at the bright side ---- you will build up your muscles brushing! ;)
Keep in mind, we haven't established that any of those spots ARE black algae. The most definitive test is to scrape some off with your fingernail, and smear it on a white card: black algae will smear dark green.
Brushing will make plaster wear through spots WORSE!
But, if you DO have black algae, a brush like thisPentair R111616 604A Algae Brush with SS Bristles, 6-Inchwill help.
