In a while it has that nice grassy look of Amano tank but on closer
inspection the tangle of
wild runners create breeding spots for all sorts of algae, beard, spot,
thread, fuzz, you name it.\
This is especially apparent across the front side of the tank where the
runners seem to be heading....

You bring up an interesting point. I had either Echinodorus Tennelus
or short type of Sagittaria and I had a simular algae problem. As a
matter of fact I just threw it all out this weekend. I didn't like
the way it was growing. I had it in my 10 gallon experimental tank.
I don't have any fish in this tank although it had goldfish for about
3 years so the substrate is full of mulm. I've been having a horrible
hair or thread algae problem as well, but I never connected the two.
I had blamed my algae problem on the fact that I've been changing the
CO2 levels a lot in this tank. They have ranged from 0-30+ppm, I'm
playing with different DIY CO2 mixtures. In addition, I have also
changed the KH from 3 degrees to 14 degrees.

Is it possible that this plant promotes algae growth. I've seen that
Egeria densa reduces some alage growth, so the opposite is true. Any
comments?
