You have to soak it in a bleach solution (cheapest out of H2O2 & excel). When the BBA turns white, it's dead. Usually takes 15 minutes or so.
And redo that when it comes back? What to do if there are fern/moss on it?
I wonder how those super clean and beautiful woods with moss in those
"hi-fashion" tanks are maintained. Or BBA can't grow in those super-balanced tanks?
In short, is it possible to prevent BBA growing on woods?
There are guidelines for BBA on plants but I've never seen one
for woods or hardscape.
