can someone please tell me what I'm doing wrong?

Manual removal helps but it'll still come back. It could still something in your rocks dieing from your Kent Carbon issue. If your upgrading anyways go rockless for a while and bite this in the butt.

Do I just need to get it all out to cook it? My tank will be ok (fish/corals) with now live rock for filtration?

Do half of your rock for now if you want and just do more water changes. I'm not a big fan of always putting my hands in the tank and disturbing things. Have you followed the Algeafix Thread? That dudes had good luck with his problem as well.

No i havent seen that one yet. If I black out the tank as well, will my corals mainly my remaining sps be ok? For how long lol..

Also my wife and I moved into my parents to save up for a down payment.. so space is non existent to set up buckets all over for cooking the rock. Would moving the rock to the sump blacked out with regular water changes serve the same purpose?

Well if you plan on manually removing the HA doing it in your sump is alot better than disturbing your display. You will still have whatever it is that is leaching out of your rocks happening. But it is a good start. Someone mentioned earlier about emerald crabs but your best bet would be a seahare if theres someone in your area that you can borrow one from.
