Natural sea water is 35ppt. Specific gravity will vary
with temperature. If you look at where 1026 is at normal
reef temperatures, in comparison to 35ppt you will see
that 1026 is not off the wall.

Personaly I like to keep my water at 1024 +- 1 with the
emphasis towards the higher.

It was only the Tang that had Ich and its a bit odd that i only did those
3 things and the Ich suddenly dissapeared. What else would have
eradicated it?

Ich is a parasite that goes through an odd lifecycle. The adults will
spend several days on the fish. They then drop off into the substrate, lay
eggs, and die. When the eggs hatch, they become free-swimming critters,
just barely visible as wiggling dots in the water. They attach themselves
to fish as they encounter them and repeat the cycle. The whole thing takes
about 10 days.

You're probably seeing the period in which the adults are laying eggs. You
can expect another occurrence within a week. This time, more of the fish
will probably get it.

I would keep the SG down to 1.023; 1.026 is too high and will dehydrate
your fish. I would also keep the UV on all the time (I do on my tank).
This won't eradicate ich, but it will kill any of the parasites that pass
through the unit while in the free-swimming stage, so it does slow down
the spread.
