It's like a black dusting on the leaves that won't really come off. It started on my Siamensis 53b and has just spread from plant to plant.

PattysAquatics Posted December 27, 2020 Share Posted December 27, 2020 Thank you for this post because I have been struggling with the same algae and not being able to get rid of it. I read maracyn can remove this. My question is to do this what are the dosing instructions? Same as box of one packet per 10 gallons a day for 5 days?

I can't even buy maracyn in my country so if that is the only treatment then I am buggered. Link to comment Share on other sites More sharing options...
