Having issues with nuisance algae

[Gichigami.reefer]

I’ve been having some issues since I tried to “rescue “ 2 fags in august with the tiniest amount of gha I dipped in H202 and put them in tank everything seemed to be going good numbers were good and all of the sudden boom it was everywhere slowly kept losing coral ( I bet atleast 15 frags lost ) but numbers were still within range and then I had tests for a few weeks with 0 no3 but i got levels back up and I’ve been doing manual removal and just completed a 3 day blackout to knock it back which seemed to help a lot but don’t want it to become a issue again. Wanting to know what’s best course of action? Dose beneficial bacteria to outcompete the gha and what I assume is Dino’s ? don’t have microscope to confirm but based on looks I’m pretty sure. Pictures for reference on parameters, what algae looks like and pictures of the frags that introduced algae , as well as before and after the “crash “ and a current picture since I’ve added some free frags from a buddy that are doing mediocre at best . I need advice or best plan moving forward ?

More bacteria is not gonna help, if anything it'll make it worse, by creating more fertilizer: nitrates+phosphates. You prolly have some extra nutrients so check your levels. Do more frequent water changes. And get a algeavore, add clean up crew/pods. If you're corals are strong, go lightless a couple of days.

Not sure I totally understand the problem, but the pics don't look bad for a newer tank. I'd let it stabilize and not do anything different for a few months. New frags dying is common and not a direct indicator of the overall system.

Maybe unpopular opinion but I would get rid of the blade or add a full spectrum light to go with it. My single blade was a gha factory and I noted significant improvement when I switched to a Noop pro v3.

I think beneficial bacteria gets a bad rap because it is over used. I think microbacter helps establishing a tank if used at half the rate or less it calls for. It won't be a dramatic immediate improvement but should shorten the process of erradication without over-competing the natural process. I dose a capful in my 40g every week(when I remember).

Oh and lots of pods
