If you wonder how efficient Amano shrimps are against BBA, here is my story. This aquarium I have used as an experimental tank; fertilizer testing, CO2, photoperiod, water flow...

We all know how stubborn this algae is and it is difficult to eradicate it even when the cause is removed. Well, it can be done with some chemicals like direct spraying with H2O2 or Excel / Easy Carbo, but these chemicals can very easily kill some sensitive plants and especially mosses. I decided for a more natural approach and give Amano shrimps a chance. This is the result;
