Are you using the iodine test? Even after complete conversion, the
idoine will still react with husks in the wort and turn dark, but
not as much as before conversion. don't worry about it.

The clarity of the runoff, and your extraction rate are the quality
indicators of your sparging method. If you're having trouble, try
letting the runoff settle, and rack off of the precipitate. everyone
should try this at least once after they think they've got their
sparging method down, just to see how much husk material actually
remains in the wort.

30 minutes is not a long enough boil. try at least 2 hours, add
irish moss, force cool, and you will immediately see a spectacular
amount of precipitate - typically 1" in the bottom of a 5 gal carboy,
more if hop pellets are used. this is the hot break, and you should
definitely rack the wort off of it.
