Black hair like strands on plants (hair algae?)
I have some very dense vallisneria at the back of my tank and today I decided they needed trimming, however in doing so I discovered they were covered in black hair, perhaps hair algae? There was also bits which had white hair too.
Thinking about it I also have this same hair like stuff on some of my other plants at the front and on a piece of bogwood, and the front glass is often covered in a light film of white or brown stuff.
Any idea what can I do about this? I do weekly water changes and my Nitrates are always around 10 - 20, not to mention the tank is fully cycled with 0 ammonia and nitrite (PH is 7.6).
27 Gallon planted: Super Dragon Betta, Neon Tetras, Honey Gourami, Rummy Nose Tetra, Checker barbs, Bolivian Ram, Otocinclus, Amano shrimp, Assassin snails.
75 Gallon Reef: Ocellaris Clownfish pair, Firefish, Royal Gramma, Bangaii Cardinal, Midas Blenny, Coral Beauty Angelfish, Cleaner Shrimp, 18+ crabs and snails

I had something similar on my driftwood, rock work and a few plant leaves. I pruned my plants being careful not to disturb the algae so the spores don't let loose. I boiled the heck out of my driftwood and rocks and scrubbed the algae with a new toothbrush until it was gone.
Here is what Lady Hobbs suggested,
"I have put my wood in a mild bleach/water solution to kill the algae on it. If's already water soaked so doesn't absorb it and I only leave the wood in the solution for a very short time. Maybe 2-3 minutes and then I drop it in a bucket of water with dechlorinatored water and let it soak in there for awhile. It can get in all the little creeves that way and not leave any algae spores to survive.
Several plants can tolerate a mild bleach solution as well. Some don't. (Very mild bleach/water solution.) Like 1 part bleach to 19 water."
If you get it cleaned up reduce the amount of time your light is on and increase your water changes for awhile. Monitor the results and adjust accordingly.
I hate that stuff.
Please remember; every keystroke has a consequence.

It's called black brush algae. Tricky to fight. You can do the bleach dip but this will almost certainly kill the vallis.
There's not too much you can for this kind of algae. Start dosing low dosage of easycarbo (2ml/daily) and make sure there's some flow in that area.
