Looks like it could be dinos... A closer pic would help a little bit... Could also be diatoms.... When was the last time you changed your ro filters and membrane?? I had something similar when I used a cheap membrane... Swapped my membrane for a good exspensive one and swapped my di resin and it went away with in 2 weeks.... Hth... If it's dinos you can use h2o2... I have a nice big thread you can read haha...
