Unfortunately its not and im on 7 or 8 weeks of vibrant. It has definitely affected the bubble algae but it hasnt died off yet. So im hoping a few more weeks and itll die off.
I used Vibrant weekly but took 3+ months for bubble and green hair algae. Bubble never came back, but either green hair algae snuck back in again or we only got 99.9% of it because GHA is back
Biopellet reactor has been the best addition to controlling our nitrates and phosphates, but we are doing manual GHA removal as well as back on Vibrant. BF swears UV makes GHA grow... lol Wishing you much luck and patience - hang in there!
