Hi everyone, My tank is about 8 months old and has a horrible outbreak of green turf algae. It is rooted, grows in clumps, has branches, but does not have the "feather or fern" of bryopsis. My astrea snails seem to eat it, but it grows faster than they have appetite for. I measure alk, phosphate, and nitrate almost daily. Alk is 8.5 - 9, phosphate tends to drop to 0 and I dose seachem phosphorous to keep it at about .04 - .08 with red sea test kit. Nitrates drop and I use seachem nitrogen to keep it 4 - 6. I have biopellets (only about 1/4 c or less on 125 gallon tank) and have some macroalgaes growing in the sump. I've been phasing out the biopellets in favor of macroalgae. 5 small fish and a few corals. I do 'overfeed' since I don't have excess nitrates or phosphates. I've been reading through the threads for both products. It seems like the Fluconazole kills bryopsis and is hit or miss with turf algae. The Vibrant claims to kill it, but several threads have people stopping use before it is gone because of cyano or other outbreaks. I do have a bit of cyano as well. Which product is better for green turf algae?
