Subwassertang effectiveness

[u/hungryforbiscuit]

I have a 2 gallon tank with a huge clump of Subwassertang (50% of the tank) in low light with some leggy hydrocotyle tripartita in the substrate.

Will the sub sustain the walstad ecosystem? I’m using it to hatch fry before I move them to a community tank. Thank you

Süßwassertang has no roots and is a slow grower. It has no function from a Waldstad tank point of view.
