No I don't. I just added sand while water was in it, I think that was probably the problem, I was just figuring that it would settle. But I just took out like 80% of the water and I'm not sure if I should fill the tank back up.
Since you have no fish in the tank it would be best to leave the filter off and let the sand settle. The sand can damage filter and clog your filter media. I don't know how long it will take to settle as different sand types settle at different paces.
