Excessive diatoms?

[Jakepen]

Hey guys, tank is six months old, currently has a clown fish, damsel, and a goby. I have what I think are diatoms, and quite a bit. I have a lot growing on my back wall, so much that I can see them swaying in the current. Let me know if these are definitely diatoms, and if I just leave them be. Oh and numbers are all undetectable; ammonia, nitrates, and phosphate.

Can you get better pics?

Yeah I can tomorrow. I mean from what I've seen as far as diatoms goes, it matches. I just want to be sure, and know if even being six months in I can still expect to see so much.

It's pretty hard to tell in the picture, but there is a lot on my wall.

Any opinions?
