No, I wouldn't vacuum the sand. It is true that the
parasite likes to attach to calcium carbonate, in
fact it has been shown that a tank with no calcium
carbonate material, will greatly if not completely
prevent the cycle of ich.

Did not know this... interesting.

But what I would do is yes you can ad the peppermint
shrimp. They will clean some, but get some cleaner
shrimp in there. If the tang is healthy, and has no
other stress factors it will heal up just fine with
some cleaner shrimp in there.

I could not catch peppermint in the other tank.
So right after work I went out to the store, picked up
one Lysmata amboinensis (they all had this "black
spot disease" so it was very hard to pick even one
with little less visible symptoms).

After lights out I introduced new shrimp to the tank
and went to sleep.

Today when I went to work I could not inspect fish,
it was sleeping behind rocks, but now, I am home
and I see fish has almost no white spots. I see
drastic change. From about 20 spots now I can
see empty places where the parasite was sitting
and maybe 2 or 3 where it is still something there.

I am not sure if the shrimp was so active or if the
parasite was ready to drop from the fish on its own.

I fed the tang generous portion of dried algae and
some meat pellets, what else can I do to help him ?

Should I continue feeding him sliced garlic?
Here is interesting article about ich and garlic:
