If you searched for advice about T-coupling groups you will have seen 
the strongly-worded advice not to use more than two or three, and 
definitely not multiple small geometrically-isolated groups.

Probably you should use make_ndx on the correct structure file and make 
(say) a solvent+ions group and a solutes group and T-couple those.
