I have a beard algae issue in my planted 180 gallon. The stuff is tough!!! Scrubbing with a brush barely fazes it. My 7-8" Flagtail cannot make a dent in it. Folks that see the tank like the look of it but I am torn. It does look natural and is healthy for the fish and clears the water. On the other hand it looks sloppy and tends cover the plants. The plants grow so fast that I can remove the badly effected leaves without much issue.....they are replaced in days. Most of the algae is on massive driftwood the largest is over 80lbs. My question is is the battle worth it?? I used peroxide on one smaller pc of wood and the algae changed color a bit and has been disappearing. Getting the big pc out will require some planning and lots of peroxide!!
