I have a newly setup 14g tropical aquarium. It has a couple of plants and a betta. The tank has been up for about 10 days now.

I have just discovered a filamentous algae growing between the leaves of some of the plants. Here is a photo of the algae as can be seen with the naked eye:

Almost life size, the thin strands is visible between the leaves of this plant.

Microscope of the strands, about 200x magnification.

Microscope of a single strand, about 400x magnification.
 
I have no idea but I think your microscope pictures are awesome.
 
I think I have some of that growing on my java moss, not sure what it is but looks very simular. Never been an issue tbh.
 
Looks like standard hair algae or could be cladophora both from low CO2 or low nutrients for the latter.
 
I have had a reply on another forum, and it was identified as Oscillatoria spp, a type of cyanobacteria.
 
They used this link as reference:

Def looks like the one in the link. If the tank is only 10days old ammonia one way or another is a good shout.
It depends if you're dosing enough ferts etc for you lighting I guess.

More importantly tho - What's your microscope and camera set up?
 
Ammonia is pretty much unmeasurable.. Have been monitoring it since I started the tank and it never changed colour. I only started dosing fertiliser yesterday, before that nothing. Lighting is strong, I have 2 x 24W PC bulbs in there.

The camera photo was taken with a Canon 5D Mark III and 100mm F2.8 IS Macro lens. Hard to get a good shot because the betta kept on showing its gills infront of the lens so I had to make do with that one. Also, through the acrylic one does not get as good pictures as through glass, especially lead free glass.

The microscope is an Olympus BX53 microscope, with 20x/0.75 and 40x/0.95 UPlanSApo objectives, and a Canon 600D camera attached to the trinoc. DIC illumination was used.
 
The ammonia doesn't have to be detectable. If you're lighting is high you're probably looking at a lack of CO2 also.
