Anyone know what this is?

So I just did a 30% water change a few days ago and today I noticed a stringy spider web like stubstance which is pink in color and I have never seen anything like it. I was curious if anyone know what it is and what caused it. Also, is it harmful to my tank, aside from it being an eye sore image.jpgimage.jpg
 
Nitrates are 0 phos were a .04 now it's only on glass no where else I guess just leave it be until it goes away on its own since its not to bad?

It looks like you just have a bit of it, so I agree with getting it out and just keeping an eye on it for now. Does your tank get any direct sunlight or has the temp been high? I got a cyano outbreak in my 12g years ago when we had a temp spike when our air conditioning unit shut down.
 
What should I do about the cyano on the glass? Leave it be and just siphon the stuff floating? It gets a little direct light but I try to keep my Shades closed. No temp spikes usually at somewhere around 77/78 degrees

Syphon it all out if you can, shut the shades totally for a few days and see if that helps. Light (and direct sunlight) can have an effect on cyano.
 
So just scrape it off the glass and siphon it? When I did that with hair algae it spread like wildfire I just don't wanna go through that again. What's the best way to go about this?
