This same principle is being used by some of the marine and brackish keepers
who are using mangrove propagules inserted in styrofoam floats in their
sumps and supplying good light for 12-14 hrs per day. These are developing a
good root system which is performing many of the functions of the trickle
filter and protein skimmer as far as water quality maintenance is concerned.
The leaves can be trimmed to minimal to keep them under control.
