hair like algae growing on my java fern
My situation is similar. My tank is a 33 gallon that I started 9 months ago. I reasently bought a large Java Fern, about 2 months ago and it has the little brown hair (Algae I guess) growing at the tips, "upward" as you said, (not to be confused with the plants little brown roots that drop down from the bottom part of the leaf). I've just performed a water change yesterday and removed a big leaf, that had a big beard of the stuff at the tip. I've noticed that the leaves that are shadded by the big leaves of my Nomaphila agustifolia hanging over it, don't have the "brown hair algae". My tank has two 59cm long, 18w (one bulb daylight & one warmlight) so 36 watts total-plus reflectors. I only just started fertilizing with "Amtra fertilizer" two water changes ago (I change 20% every 2 weeks), this is when I dose but only HALF the recommended dose with the new water after it's been conditioned. I've read that we should all learn to live with a little bit of algae and I agree, I just don't like when it takes over my plants. I have some algae growing on a big conch (shell) and a big piece of drift wood and it doesn't look bad it makes it look more natural. These are my control points, I read you should always leave some algae growing on a rock or piece of wood that you don't disturb and this will keep you from having big out bursts.
I don't know if any of this will help. I've been at this for a year now, so I'm still learning too.
