Diatoms help please.

[SteveCGY]

So my diatoms is at an all time high and just covering my rocks in the thick film. I don't have the means to do a water change today but should I blow them all off and stir the sand bed and see what my skimmer can get or just leave it and let it run it's course. I don't want my corals to get over run by it but at the same time I don't want to blast it all off then have really bad water that things start to die. Any thoughts or suggestions for this?
