BIG TROUBLE!! Need advice please.

What does this mean? Would dosing zeo bak suffice?

The before picture of the display was probably 2 months ago or so... things got WAY better after that, and then BOOM!!

If you have algae growing in the tank - especially copious amounts - it will suck all the phosphate and nitrate out of the water so your kit can't detect it. If there is algae there is phosphate, can't argue that. Plus, when you added that frag tank on the algae bloomed in there like no tomorrow pointing to nutrient issues. Phosphate is a coral killer. Algae can help in a way by sucking the nutrients out o the water, but many algae also release toxins used as an offense tactic to help themselves spread.

The rocks are poorly designed for flow, and look like they collect a lot of detritus. I also notice that many of the rocks are from dry base rock, which I really don't like. I've seen algae blooms like this when using base rock so many times. Many base rocks will leech phosphate because they were alive at one point. Other base rocks are too dense to colonize anaerobic bacteria so have no ability to process nitrate.

It does not appear to be a safe place for SPS corals. I would suggest you at least use a siphon to suck out algae as you scrape it off the back glass (and anywhere else). If you're not using a filter sock, I would suggest you put one on the tank at least while you are getting the algae under control.

I have not tried Carbon Dosing. I think that I will. I do have some questions about it though. I recently added GFO, and more importantly added the right amount as per the BRS reef calculator. My PO4 went from 0.20 on the hanna, down to 0.10 with too little GFO, and down to 0.00 with the right amount. At each step, I could see a distinct decrease in the growth of the hair algae. I still have issues with blooms, but all levels are undetectable, adn the growth has slowed significantly. Would I be OK to start Vodka dosing right now? Would I be smarter to take the hit on sleep, and properly set up my Zeo system? Can you dose vodka and run zeo at the same time? What about N/P pellets? I have them, and a reactor, but for some reason it takes a lot of work for me to get proper tumbling out of them... they make me ANGRY!! lol.

I don't notice much in the way of detritus at all actually. I did for a while because I was waiting for a VERY long time for my 6105's to show up, and then had a power supply issue with my wavebox, but now that the proper flow is in there, I see no detritus. You may be on to something with the dry base rock... I can't confirm or deny. That is however one of the few things that changed from the old tank to this one.
