Starting my first day treating byropsis algea with fluconazole , been fighting this stuff for over a year , did the tech m for 2 months , all it did was slow it down , randomly saw a bunch of people having success using fluconazole so before I tear my tank down I'm gonna give this a try . For anyone battling this stuff you should check out fluconazole, stuff may be the miracle cure for this stuff , wish me luck I keep you posted
