Laugh do you have any updates?
Also, I've been doing some pm work in larger tanks and wanted to kick the info up top to save retyping, this poster spot treated a few rocks but had some left in the display and we were considering whole tank dosing to catch the last batch of gha in inaccessible areas

Hello!
I do not blame you for not wanting to drain and treat a 75! My gallon reef spoils me rotten lol.
Can you pull back up the thread with pics of your tank so we can collect all the experiments in one place, a full tank shot and then a couple close ups of the leftover gha
I'll tell you where I'm heading-a modified whole tank dose I nerdily termed a submerged spot treatment, dosing the actual spots underwater, with the pumps off
Just that brief method of contact before it disperses into the tank will zap gha, once its truly all gone you may or may not have to adjust phosphate levels to stop it, but its highly possible it might only slightly come back like twice a year after eradication and two spot treatments a year on a dime sized spot will maintain it.
So you can see how adding peroxide to the top water requires higher concentrations than actually hitting the patch...pretty simple mod huh
So envision extending even that method even further-slow, pulsed delivery right at the base of the gha patch so it covers the gha slowly as it leaks out into the tank, using ideally a diabetic syringe and needle or secondarily a little plastic doser I put a picture of in the thread last week, you slowly squeeze the peroxide right into the base of the gha
Your sensitive organism is the fire shrimp, nothing else. You inject, leave pumps off 5 mins, turn back on.
Depending on what pics show, we know if you can treat all at once or if you break up the treatments over a few days to lessen the dissolved amounts being mindful of the fire shrimp
Gha is highly sensitive to peroxide this will zap it clean and based on regrowth or actual phosphate testing we can create a better plan for prevention
