To address your immediate problem while you learn: I'd recommend reducing input (but not so much as to starve your animals) and manual extraction--every day. It's a lot of work, yup. Do weekly water changes (5-10%) with quality RO water. That should keep things from going off the deep end until you get your feet under you. It likely won't be pretty, but it should be manageable until you can figure out a real solution for your particular tank and maintenance routine.
Learning:
IMO, research the internet on nutrient control in reef tanks. There really is a ton of well written information out there. http://www.advancedaquarist.com is a decent starting point and the authors there are generally worth following wherever you can find them. There are several other good sources. Google is your friend.
Nutrient control is a fairly complex topic and it's worth actually studying. And what I mean is by "studying" is reading a bunch of articles online and in books, working through unfamiliar/difficult concepts, and internalizing the information. I guarantee you that if you do this, it's very possible to never have algae problems again. I speak from personal experience.
Following advice you get in forums can be problematic. Not because people have bad information necessarily, but because the information is generally incomplete and there is implied context. For example, the advisor assumes you know about skimming and topoff issues, but you don't.
For simple topics, simple advice is fine, but IMO I don't think this is one of those topics. There's just too many details that you have to know about.
