Something in my tank is CRASHING!!!

Hello,
I'm getting discouraged and could use some help troubleshooting an issue (or three) with my tank.
I will first preface this by saying my fish and mobile inverts (crabs, shrimp, starfish, etc) seem to be doing GREAT in my 1 year old 55 gallon reef. The problems are (they may or may not be related to one another): I have had an explosion of SEVERAL different kinds of algae lately. I have a very short green kind that sticks to the glass, a dark green hair algae on the bottom, and another purple/maroon-type algae (hairy) that is also growing on my rocks, etc.
The other problem is that my corals are looking AWFUL!! My xenias are super skinny and not pulsing. They look like they are on their last leg...my pink zoos are also looking pretty pathetic (for whatever reason). Even my pink leather--who has been hanging in there through this whole thing--is starting to look a little ill.
Here are my readings and what I have done:
pH: 8.4
ammonia: 0
nitrites: 0
nitrates: 15
calcium: 280 ppm (a bit low, I know, but I have just recently switched from Instant Ocean Salt to Oceanic)
temperature: 80
Can anyone give me any ideas what the problem could be an what I can do to help it?? I have tried big and frequent water changes, and the problem just seems to be getting worse (I use RO water). I'm trying so hard to do everything right and my tank just looks like its dying!! I really would like to solve this before whatever it is starts affecting my poor fish!
Thanks in advance for the help...

The bulbs are very new (I bought the lights...250watt pc's...about 2 months ago). I have not yet done a phosphate test. My mom has a kit and I will be doing that tomorrow.

new bulbs will sometimes cause more of an algae breakout than bulbs that are too old. reduce the amount of time the lights are on for a while especially if you went up in wattage.

you might also want to try to manually remove some of the algae. be careful not to disturb the sandbed.

I have also recently decreased the amount of time the bulbs are on...and have been manually removing some algae. I think it may have helped a little...I guess I will just continue and be patient with the process.
What could be the issue with my corals???

phosphates will effect corals as well as a sudden increase in lighting wattage and lamp type. corals need to be light acclimated. other things could be lack of trace elements in old saltmix, xenia will benefit from the addition of iodine. my tank lights got left on for 15 hours and my toadstool looked like crap (gray and limp). it took about 9 days before it got its color back and extended its polyps.

I will be interested to find out where my phosphates are at tomorrow...
As far as light acclimation, I got the corals from tanks that had stronger MH lighting. Maybe my lights are not strong enough?? Most of them I put in after I got my new lights.

low calcium & phosphates and nitrates.
