Algae is to the aquascaper as weeds are to the gardener. It's a never ending battle to keep your hard work from being consumed in a gooey, smelly mess. Granted, we'll never be 100% victorious, since some level of algae is natural, but it still we do everything short of using chemicals (and some people even use these in a desperate last ditch attempt) to try to get the upper hand.While most aquascapers and planted aquarium hobbyists have probably encountered nearly every type of algae in their careers, we all have a particular type of algae we dread the most. For me, it used to be Cladophora sp., but now, I just cannot seem to kick this black brush algae (BBA). It's sprouted up all over the place and despite having my CO2 high enough to make my fish gasp it doesn't seem to want to go away. So what type of algae do you dread the most?
