E najas is not to bad to remove compared to others plants. It has a distinct
serration on each leaf edge and the plant gets "crunchy" if grown in harder
waters and feathery if in softer water like many other plants. Looks like
many pic's of L. major. This plant, najas, branches more than these others.
Check the Baensch vol 2 I think for a better ID. It can be quite decorative
bu8t needs pruning here and there(1-2 weeks).
Perhaps adding some crypts instead will solve your maintenance misery.
