Hi Peter,
In nature, Aldrovanda thrives in dystrophic waters characterized by
considerable levels of humic acids which result from the decomposition of
plant rests. Though I never tried it, I believe that Tetra's Blackwater
Extract might help to create the right water type for the Waterwheel Plant.
No idea if it appreciates the extra vitamins.
To keep the risk minimized, it is advisable to start with adding small
amounts of extract. Carefully watch how the plant responds.
In short the medium should be slightly acid, dystrophic and contain
microorganisms.
Hope this helps.
