It's probably Gelbstof from decomposing algae. It's fairly normal and Carbon will remove it. It will significantly decrease the amount of light your corals receive.
The test for it is to tape a white sheet of paper at one end of your tank and look at it from the far end to see the actual color of your water.

Even though I am 100% sure Bang is right... Ammonia will turn water yellow also

yeah. 0 ammonia in my tank though. trites and trates are VERY low if not nonexistant.
Carbon or waterchanges are the only ways I know of to remove this yellow/green stuff. Typically, running GAC in a high flow area so water is forced through it for 48 hours will remove it. If you have a lot of live rock you may need to do it once a month or so. Use the white paper method to determine how often to use the GAC.
The GAC will only work once, you'll need fresh GAC every time.
