White Fluffy Algae HELP!!

Over the last week I noticed a white fluffy looking 'algae' growing on my java moss and grass. I did an internet search but couldnt find anything like it.

I trimmed up the moss and the grass and siphoned the cut bits away as best I could, I've just spotted it growing on one of my air stones now too, I'll get my son to take a photo later but does anyone have any idea what it could be please?

I've boookmarked this page, thanks Steve. I seem to have some green strandy and purple algae growing.

 I trimmed off the grass and moss but if you look you can see its grown back on both its spreading to the broad leafed plants now.

I cant find anything like it in the link to the doc you posted Steve

Apologies for the multiple edits

I cleaned as much out as I could yesterday and its actually more gelatinous than furry, really nasty stuff and thanks for the reply steve, lets hope it'll go then. The fish don't seem in the slightest bit interested in it, even the ottos turn their noses up at it

The fact that Esha 2000 gets rid of this stuff confirms my suggestion above that it is a bacterial growth and NOT algae. Esha 2000 should be totally ineffective against algae.
