Need help with dusty sand.

[Icefire]

Well I got 135lbs of mortar sand (100% crushed marble) which is 85% sugar sized and I guess 15% dust even after a small rinse.

Sand was put 12h ago, water is milky white, already 1/4" white very fine/smooth layer on the top.

Even if water clear up in 2-3 day, I will have a sandstorm with any fish...

Any way to screen it/ remove the dust?

Once dust free it would be quite perfect particule size.

I washed out my sand thoroughly before adding to the tank, it was milky for a day and went away, the other way is put in a aqua clear 500 hob filter with a filter and let it run until the fine particles are absorb in the filter. The other option is let the bacterial grow on the sand and it will settle, but takes some time!
