Tile question

I had never used pre-mixed grout before, but the salesman gave my girl some pitch about it and she insisted that we were going to use it.

When I was applying it, it was maybe a little thicker than I like it, and it stuck to the tile a little tighter than I would like (requiring more pressure with the sponge to wipe it off), but I did not notice anything unusual in the application.  The gaps looked filled and nice.

Now that it is dry, it seems like the gaps are only filled about 7/8 of the way to the top.  Is it safe to add more grout on top to fill the remainder?  It is a bathroom, so I don't want low spots of standing water.

Second question, the only ever bathroom I have ever tiled, I put grout between the tiles at the tub line, but not between the tile and the tub.  There I used a silicone caulk which matched the tile.  For the life of me I can't remember where that concept came from, but I did it again in this one.  Does it seem like that can create a problem?

Thanks folks!

Yeah, all those premixed products suck, when it comes to the application of them.  If you filled the lines tight, no need to reapply any more.  Chances are that the layers wouldn't bond together well, and you would have the top layer scaling off in a short period of time. 

You did well to use the grout caulk along the seam of the tub and tile.  It will remain flexible and watertight for a good number of years.
