Dear all experts, need help on green hair & black hair algae
my tank got alot green hair algae, on tank glasses, plant leaves, and have a minority of black hair algae. i got OTO fish, but seem they not eating them.
how to get rid of them?
Otos wont touch it. U sometimes see them try to nibble on it, but once they realize it's hair algae, they'll get away from it.
Photoperiod needs to be reduced.
Nutrient wise, some say u should maintain so that ur other plants will grow well n ur tank will be cycled faster n the algae will go away. Some say need to reduce so that the algae will not have access to nutrition as well. I tried both way, didnt really help. Maybe cos my utricularia grows so slow.
U can try dosing excel. I found out that once u double the dose, the algae will start turning brown n become fragile and u can easily suck them out or brush them off. But if there is livestock, need to monitor them scared overdose.
