       Type of Algae                             Cause                                           Solutions
Black Beard Algae (BBA) Low CO2                                           Add CO2, trim, spot treat with Excel
Blue Green Algae (BGA)            Low nitrate                             Blackout + add nitrate
Cladophora                        Low nitrate + Low CO2                   Add nitrate, add CO2
Diatoms                           Excess Silicates, Low light             Wait, add catfish, use RO water/sponge
Green Dust Algae (GDA) Spores                                             Wait out life cycle, remove + WC
Green Spot Algae (GSA) Low phosphate (+ Low CO2?) Add phosphate, possibly add CO2
Green Water (GW)                  Ammonia + High light                    Reduce light, wait, small WC, UV filter
Hair Algae                        Excess nutrients, silicates             WC, Excel, reduce food, is something limited?
Hydra                             Stowaway in live food                   Use cleaner live foods, flubendazole, H2O2
Milky Water                       Bacteria bloom                          Wait out, protect filter, add fish slowly
Staghorn                          Ammonia + Low CO2                       Remove, WC, protect filter, Excel
String Algae           Excess nutrients             WC + get biofilter working
WC = Water Change, CO2 = Carbon Dioxide, H2O2 = Hydrogen Peroxide
