Hello, I currently have a GHA outbreak which I’m addressing, but the thing that’s concerning me is that there’s GHA growing on the underside of my branching GSP. I know that usually only happens on dead or dying corals, but the polyps are completely open. Wondering if this indicates a flow problem? The flow might be a bit low in this portion of my tank. Any advice is appreciated!
GHA on underside of branching GSP

How old is your tank? What are your nitrates and phosphates like currently?
For the meantime, shouldn't be a problem taking out the branching GSP and spraying with hydrogen peroxide in the affected areas. Give it a minute then back in the tank. The GSP will be angry for a bit, maybe a few days, but it bounces back quick and will likely do better without the GHA growing on it.

Edit: looks like that brGSP is anchored onto a big rock pretty well. That's not easy to remove is it?
For in-tank treatment of GHA, I've had some luck with a baby bottle nipple stuck on the end of a pipette, which I lower into the tank without letting tank water into the nipple, then slowly dripping the H2O2 onto the affected surface once the air dome of the nipple is covering the spot.

I have had the tank running for about 5 months and slacked on water changes for about 2 weeks then This bloom popped up… I’m returning to my old water change schedule and decreasing feeding a bit to try to (slowly) combat the GHA outbreak. I’m not too concerned about the GHA outbreak as I think returning back to my old WC schedule and decreasing feeding by a bit will take care of the outbreak. I was just worried that the GHA growing on the coral meant that it was dying on those parts as I’ve read that algae only grows on dying corals. My question I’m trying to figure out from the post is that if the algae is a sign of the coral dying?
your gsp will be fine. I'm currently in the clear(fingers crossed), but I've had some horrible GHA in the past. It gets tangled in the GSP, then starts growing on the base of it. It can get irritated long term, but I would always just pull off the bulk of the algae from the coral(there would always be some wispy strands left). those few strands would eventually regrow and I'd repeat the process, but it never harmed the corals unless they were totally smothered and not getting light.
