I would just give it time to settle. A second filter is a good idea. The ratings on filters is always uinderestimated IMO. Better to over-filter a bit than under-filter. ARe you doing a fishless cycle?

I'm not familiar with your particular substrate (aka gravel), but if you wait 24 to 48 hours most of the dust should settle out and then you can siphon it from the gravel. Repeat as needed.
