my aquarium is 1 year old but the brown algae (that appears on the substrate when aquarium is new) has reappeared. i think it’s because of a few silly mistakes i did (like using ciano meds to get rid of it, twice, thinking it’s cianobacteria).
how to get rid of the brown algae on substrate without flushing it (that would greatly stress my full-of-life aquarium)?
