My tank has been running for about 3 months now. I've notice that the past few weeks my tank has this slimy buildup on the top of my water. Is this bad? How do i get rid of it. I have a 75 gallon, two green chromis and two clownfish

It sounds like a protein buildup. Not uncommon in a fish only tank.

Consider a skimmer of some kind. or try the paper towel trick by setting a paper towel on the surface and quickly removing it.

Is this the ghost of a fish keeper from the past or is he ALIVE?

Alive, for now at least.. Howdy Bob!

Yes, I may start up a tank or two before too long. Gotta get in the mood..

No slimy film for me though.

Surface extraction is what you need to remove protein buildup, i can this the "oil slick".
A drilled overflow box with remote sump is the best option, I think Ehiem manufactures a device to work in conjuction with canister filters, you could easily retro fit to any cannister, I had one back in the late 80's :-)
