Budding Problem with Blue Green Algae (Cyanobacteria)
So I think I have a budding cyanobacteria problem in my 10 gal divided betta splendens tank, and I'm getting mixed reviews of how to treat it. I want to stop this early before I have a blue-green tank. The tank has been running about 3 months now, is fully cycled, and only has duckweed, one anubias (recently added, tied to driftwood), and some java fern that is doing poorly (I'm trying to revive it as it was the only one at the store at the time). It's cycled, heated, and has a home-made bubble filter. The light is not exactly what I want: I have a crappy hood that uses two screw-in light bulbs (wish I could remember the wattage and kelvins on them). In order to upgrade it would be a total of around $80; I can do this as soon as I get a summer job. The parameters are: pH 7, ammonia 0ppm, nitrite 0 ppm, nitrate 0ppm, GH 3, and KH 3. I'm not dosing with any ferts. I want to have more plants and a better light in there before I start. What is my best option for beating back this algae bug before it becomes an algae monster?
