It looks purple and fuzzy and it's all over my fake plants. I dont mind the look of it and I have alage on my rocks and back glass on purpose because it looks more natural. I just want to know the type of algae.
Active ingredient in 'liquid CO2' (like flourish excel), and is an algaecide. Some plants like vals and liverworts also respond negatively to glut as well.
When using it you can dose for the entire tank by simply adding it in or using a syringe with filter equipment turned off. You target the areas with bad build up of algae, wait a couple of minutes to fry up the algae (it turn a bright red) and then turn equipment back on.
Edit: H2O2 works similar to glut, and can easily be substituted for glut.
