Be very careful if you choose to do the bleach treatment to riccia. Mine
was heavily infested with red algae so the 3 minute treatment was performed
this past Tuesday. It looked fine after the treatment, but each day finds
it becoming paler and paler. I do not know if it will survive. Luckily, I
have a few small pieces in other, algae free tanks.
