So, I have n algae question. Two of the tall artificial plants in my tank (they are side by side) have some fuzzy dark green algae growing on them, and seems that it is just getting longer. Water parameters are ammonia 0, nitrite 0, pH 7.5 The two honey gouramis seem to like nibbling on it but there is no way they can eat it all! 1)Is this stuff harmful to have in the tank or just annoying? 2)How can I get rid of it, safely? tried to pull the threads off but good luck with that!
