Type of algae	Cause	Solution
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 more CO2
Green Water (GW)	Ammonia + high light	Reduce light, Wait, Small WC, UV filter
Hair Algae	Excess nutrients, silicates	WC, Excel, feed less, is something limited?
Hydra	Stowaway in live food	Use cleaner live food, flubendazole, H2O2
Milky Water	Bacteria bloom	Wait out, protect filter, add fish slowly
Staghorn	Ammonia + low CO2	Remove, WC, protect filter, Excel
