Sulfur smell (how to get rid of)

[Pyg]

My local brew store has been doing an apple cider buy ever couple months.
I got 5 gallons of NY cider in December.
Added 5 Camden tabs let it sit over noght
Added nutrient (according to directions )
Added pectin (according to directions)

Once ferment I noticed the strong sulfur smell.
I racked the batch into 3 gallon carboy and a 1 & half
The 1 and half I added black cherries and it started fermenting again. This batch no longer has the smell

How ever the 3 gallon carboy does. My local home brew place suggested throwing some Pennie’s in. They don’t stock what ever chemical (copper something sulphate) to add.

I asked about multiple splash rack with my All in One Vaccume pump.
Since they knew nothing about vacuum pumps they were afraid of oxidation and could not advise.

So it is safe to just rack back and forth with the vacuum pump?

Is there an easier method?
Trying to figure out how to rectify this smell before I get another 5 gallons.

Thanks in advance for any advise.

I'd add some nutrients/energizer and see if I could get any more fermentation out of it.

Sulfur could be from stressed yeast, not enough nutrients, or just normal for that yeast. A sanitized bit of copper pipe/wire in the brew for an hour or 3 should pull the sulfur compounds out.

With Sulfur smell, most of the time, waiting is the best solution. It will go away.
