Huge algae die-off??

Since I upgraded my filtration, I've had large amounts of coralline algae disappear, as well as another type of algae that was all over the place and looked like montipora the way it grew out like shelves. At the same time I upgraded my filtration, I also upgraded my lights. I would have thought I would get more algae growth, not lose it all together!
I'm also having problems with all LPS corals. Some are not growing at all and some are dying off, such as my flowerpot. It has faired the worst. Most others are just stagnant and don't want to open up sometimes. My SPS on the other hand has gone haywire with huge amounts of growth and polyp extension.
Could it be that my water is too clean?
Parameters are as follows:
Nitrates: 0
Nitrite: 0
Phosphates: 0
Ammo: 0
Ph : 8.2
SG: 1.026

I started running carbon about 2 weeks ago because my colt coral and GSP wouldn't open at all. About 12 hours after adding it they bounced back and are looking better. However, they're still not like they were. What is really troubling me is the algae die-off. I'm thinking that whatever is causing that, is causing the coral issues as well.
I've always had trace amounts of nitrates and battled elevated levels of phosphates all the time
Hair algae was always a problem. Now, it's non-existent along with everything else!
Chaeto algae and halameda in the fuge are growing well though.
Any ideas what the issue could be?

What is your calcium reading? Also what type and brand of lighting do you have?

Possible issue with calcium, alk, or mag.

I don't have an alk or mag test kit
I'm thinking I'm gonna have to order those. I'm clueless as to how the mag would affect the algae or LPS. My understanding was that a healthy level of mag (1250-1350) helps sustain a stable calcium level. I know corals use the mag, but I never understood the importance. I guess I just never dug that deep. I understand Alk and ph go hand in hand but that's something else I haven't been well acquainted with.

Would it hurt to dose mag? I used to dose it but was advised not to dose something I don't have the ability to test. Same with iodine. I try to sustain the calcium with my pwc's and haven't dosed it for a while. It steadily hangs around 420-450 so I didn't see a great need to dose it.
I have however been dosing "Fuel" by aqua vitro twice a week.

I'd be less concerned about mag and more interested in the alk level. But yes, don't dose if you don't test.

In terms of fuel, I've used it as well but haven't seen any benefit besides it helping my algae grow.

I had the Alk and ph tested yesterday at my LFS and he said it was at 2-3, I'm assuming dkh. He said it was fine but my ph was a little low at 8.1.
He said that was strange being that normally if ph is low, then Alk is high and vice versa. He said add buffer and keep an eye on it. He also said I'd be better off talking to the owner-his son who is a marine biologist on Thursday and he would know better what's going on and what to do. I just thought I'd come and pick your brain in the mean time.

Oh I forgot to mention he tested calcium and it came out pretty low at 350. However, the week before it tested at 420 not sure why the sudden drop but I got it back up to around 450 yesterday after dosing reef code B.

What kind of filtration did you upgrade to?
