diamond brite "streaking"...

[kim]

we just put in a new pool and definently selected the diamond brite over pebble tec because of the smoother surface. our diamond brite doesn't hurt our feet or the feet of our young children and we've been in it daily for the last 3 weeks. however, one problem that we've noticed with the beautiful midnight blue color is that there are huge (like 2-3' wide and 5-6' long in the deep end) white streaks in the color...places where the pebble is mostly white in huge contrast to the blue and you can definently see the sweep marks in it. there is nothing "natural" looking to it. anyone else have this problem?
