I have some of Hydrotriche hottoniiflora growing in my open top tank and
they flowered once ( nice small white-yellow flowers ). After flowering,
the leaves changed from green to brown color as if they died ( old
leaves are still intact ) and new stems developed. It seems that they
like strong lighting ( growing directly under my MV ). Water parameter
are 2 GH, 1 KH, pH 6.8, temp. 28 C ( ~ 82 F ).
IMO, not very difficult to grow.

I read somewhere in the Krib that protein skimmer can be used to clear
green water by collecting the unicellular algae. Perhaps it can also be
used to collect other suspended solids such as clay particles, etc. I
saw some brownish foam on my tank side where the bubbles from my CO2
diffuser float. Unfortunately, I don't own a protein skimmer to
experiment with.
