Hydrogen Peroxide for Bubble Algae

[lastlight]

The resiliency of this algae just amazes (and disgusts) me.

I have been detailing ALL of my rockwork nightly. None of my new rock grows valonia yet but I can carefully pry the bubbles off, net them and come back the next DAY and in many spots new bubbles have grown - sometimes just as big as the day before

Valonia is damn near indestructible! Just when you think you've got it licked and let your guard down for a moment, there they are again.
