Severum proof plant

[JMLenke]

NAJA GRASS.

It grows in water, it doesnt matter the conditions. It WILL grow faster then a single severum (possibly 2) can eat.

I have pulled 4 pounds of it out of my 55 and I probably have another pound of it still in there.

Also I am pretty sure that even if you cant get anything else to grow you COULD grow naja grass..
