Qiagen RNeasy: Early precipitate??

I am attempting to purify RNA from herring embryos. After homogenization
in the lysis buffer I add the 70% EtOH and a precipitate forms. This
precipitate blocks the spin column if the entire solution is applied to
it so I have been spinning down the precipitate and applying the
supernatant to the spin column. Am I blundering? Is the RNA likely to be
in the supernatant or the pellet?? I am currently unable to check the
product of the purification on a gel since I'm sampling in the field.
Any efforts to lay my mind at rest on this issue would be greatly
