may have solved my DSB / root problem 
now i am curious about non-rooting plants and all algae types out there.
freshwater only
for root types it's classfied as rhizoids (grows fine hairs that attach to objects) instead of any intensive root system
mosses, lichens, we're familiar with these
marine systems have their macro-algae, ... they can't be the only one, ... what is there for freshwater.

It just occured to me that a DSB might actually be a pretty bad idea for a self-contained ecosystem. What happens to your nitrogenous waste? It gets turned into nitrate then nitrogen gas. Then what? It off-gases, effectively permanently removing itself from your system. It needs to be replaced.
I really don't think that depending on cyanobacteria is a good idea for a number of reasons. It's quite ugly, makes the tank smell bad, and I believe it's toxic to some degree, so the number of fish/critters that eat it is pretty limited.

come get me tang police!
Are we talking Self contained as in, sealed off from the atmosphere?
not a sealed self-sustaining tank
not all cyanobacteria is toxic
not all cyanobacteria does that slimy covering
some form symbiotic relationships with various plants
the first i heard of was azolla, found out that cyano has a nervtoxin, so i started searching again, ... species of hornwort (not sure what aquatic species, or if these are toxic as well)
i'm aware of problems with a DSB converting nutrients into gas forms that would be lost permanently, ... the most obvious is nitrogen, ... and as it's the most significant, it's a pretty big concern, you are absolutly right, a DSB does create that problem
been looking at alternative cyano sources that aren't such an eye-sore, hopefully sources that won't be visible
i don't know how much i would need as the plants will also be trying to use ammonium & nitrates, ... so i don't know how much is left, ... regardless even a fraction of a percent lost is still lost, ... and needs a way to get it back
one person on another forum commented he had cyano in his tank, he ignored it, it reached a peak level, ... with plants it died back some, still had it, ... i won't take this as gospel, but it sounds like cyano will only grow as much as is needed, ... other sources i've come across for "causes of cyano" sounds like they agree this would be the case, but dono, i'm not going to throw random cyano strains in their, i want to know exactly what is going in.
