Your algae growth suggests that your other plants are not growing
strongly. When they do, the algae can't compete. It's growth just
says there are nutrients not being grabbed by stronger plants. You
are surely right to point to poor growth by your other plants. Jan
and others will make suggestions about helping them have a growth
environment. You can pull the string algae with a brush and remove
the nutrients it has captured. Pulling it is an aesthetic decision.
It will die back once it gets out-competed.
