Possible scutariella japonica - H2O2 or salt dip?

[Chickadee27 47]

Just noticed that a few of my red cherry shrimp have something white around their mouths. I'm unable to get a decent pic, but I found plenty online that look identical to what I'm seeing. I'm fairly sure it's scutariella japonica. It appears that a salt dip is the best treatment. However, it's going to be very hard to catch the affected shrimp since they mostly hide in the driftwood.

Then I found a YouTube video saying that hydrogen peroxide in the tank would also treat SJ. He referenced this Marks Shrimp Tanks video.

I watched the video, but he doesn't specifically mention H2O2 for treatment of parasites, only algae. I do have a brown algae problem, so it would be nice if the H2O2 treated both. But will it also treat the SJ safely?

I'm also confused about the measurements and conversion he listed. He said to use 1.5 ml of H2O2 per 4.5 liters or 1 US gallon. But it was pointed out in the comments that a US gallon is actually 3.785 liters. Before I delve too far into this, can the knowledgeable people here first tell me if H2O2 is safe and effective for treating SJ? Or should I stick to a salt dip? Treating the whole tank would be a lot easier, but I understand that could cause other problems. I do plan to remove the snails and guppies before I do anything.

I've never heard H2O2 for treating SJ.
The standard treatment is aquarium salt. 1 tablespoon per 5 gallons. Treat the whole tank, dips take forever. 2 week treatment. And remove every molt you can find during that time to prevent it from spreading.

He said to use 1.5 ml of H2O2 per 4.5 liters or 1 US gallon.

He mixed up his gallons.
1 US gallon = 3.8 litres
1 Imperial gallon = 4.5 litres

I don't know about shrimp but I have installed plenty of H2O2 to my aquariums.
1-3ml per gallon is safe.
Start low and work up watching for issues.
Like most meds light degrades it so lights out install will give the best longevity. Also makes monitoring difficult.
That being said I always expected first use in an aquarium will last no longer than 12 hours as organics also degrade it.
As you work up with consecutive treatments it may stay active longer.
