What's this? I used Microscope

[JM Kang]

I used a cheap microscope to look at what might be green algae, dinos, or cyano in my tank, but I still have no idea what it is. It's not a high-end microscope, so the image quality isn't the best. Could anyone knowledgeable take a look and help me identify it?

I would say a bunch of filamentous green algae (Cyanos usually move, get discolored in reef tanks to more red/purple, and don't really branch)

The rest seems like detritus or bacterial biofilm. Hard to tell from the overall quality.

Check out my microscopy thread if you find more interesting things you can't identify, but obviously you can always simply ask in a thread like this one

Wow, what magnification is needed to get a shot like the one in the post?

The image quality depends mostly on optics (well designed objectives) and the illuminaton technique. Your microscope uses simple bright-field which is a good "alround" method but specimen appear flat and translucent things can sometimes become very hard to see. That's why there are other techniques which can help with that:

Dark-field for example doesn't illuminate the specimen from below, but instead from the sides and the background appears dark. The first posts of the clownfish eggs were created in dark-field.

Most other images were taken using "Differential Interference Contrast" (DIC) which is a very advanced illuminaton technique using a polarizer, a prism, followed by the light passing through the specimen, then through another prism and another polarizer. This gives a "3D" impression of the specimen which otherwise would look flat.

Regarding magnification you will have to name the specific post/image what magnification would be required. Note that everything beyond 1000x with a light microscope is pretty much worthless as visible light can't resolve more detail. It's like a "digital zoom" at that point, nothing new gets revealed.
