I had an infestation of this same thing in my tank, I call it BBA for black
brush algae. I read somewhere that BBA likes iron. I controlled it by 
decreasing the PMDD dose, that I figure now was way above the reasonable
level for my tank. I was overdosing based on iron test kit readings that
were too low. 

With the lower PMDD, the BBA died quickly, in a matter of days, but the dead 
pieces are hard to rid. They stick like glued to stones, glass and plant 
leaves. I removed whatever I could manually and now I just wait until the 
hardier parts eventually decay and detach by themselves. The tank is 
practically clean of algae now except for the green spot variety in high 
lit areas.

Because of the decreased PMDD, some plants developed iron deficiency symptoms
that I'm correcting by *SLOWLY* increasing back the dayly dose. The first
plant to show deficiency was E. tenellus, followed by new leaves of
E. bleheri. They are slowly getting back to their previous colors and no
algae came back so far.

I notice that your chain sword shows the same deficiency symptoms that mine 
showed, whitish new leaves, so I'm not sure what you should do. Maybe the 
iron level in your tank is already low and not the culprit for the BBA 
bloom ? Is the BBA clearly taking over the tank or is it in a sort of 
steady state regime ? 

Btw, nice tank !
