Strange flat curely algae on glass (and gravel?)

I'm seeing a new algae I've not seen before on my aquarium's glass. It occurs in an area of high current and medium light. It's very spotty and grows in short thready curls. It will show up even after a couple days after a 50% weekly water change with IE dosing.

Anyone know what it is?



My pH has been very low (6.0-6.2) lately as a result of increasing CO2 to get rid of it (not helping). I rolled by my CO2 to it's original levels as a result of an Amano dying (and possibly an Otto, although that could have been due to harassment from new Odessa Barbs).

Typical parameter before a water change:
NO3: 10ppm
PhO4: .5ppm
KH: 4 degrees
GH: 5 degrees
Temp: 79F

Regards,

Will

Looks like oedogonium. The stuff's a pain in the ass to kill. When I was testing algaecides I used this as my model species..It survived copper based treatment quite well...I'd say hit it with excel directly or H2O2.

I have noticed some short-length hair algae on some plants which looks like the pics of oedogonium. The strands on the glass, however, is strange in that for the strands in the patches I see, the entire strand is stuck to the glass, rather than just one end of a strand. So the effect is a patch of curly threads flattened to the glass rather than a hairy appearance. I've never seen it before... Weird and annoying!

I have only seen this type of algae when I took some seed algae from a local water source. I wish I would of known how to deal with this algae then.

I think the oedogonium species may be different but I think it might be it. It's pretty common in ponds and what not. Actually I think I have it in my outdoor tank ( used to at least).

I would love to see that under a microscope to find out what that is! If you are interested in shipping me some, shoot me a pm and I'll give you a for sure id.

Without Algae, death of mankind would be inevitable.
