It sounds like Aquasoil and Powersand mixed. Since you have already got it out to dry, I would allow it to do so completely.
What I would do is separate out a portion of this mix that you would estimate to make a layer 1/2" to 1" thick. Pick out the Powersand grains from that portion and set aside the "clean" Aquasoil. I would not wash or rinse any of the substrate. The idea would be to minimize "dust" forming which would be broken down Aquasoil grains.
I would then place the Powersand grains on the tank bottom then gently pour the dry Aquasoil/Powersand mix over that and shape your substrate to your desired elevations. Place any hard scape items in the tank and finalize there position. When you are satisfied with your hard scape look, slowly sprinkle in the dry "clean" Aquasoil. Adjust the height of your stones and or driftwood pieces by lifting them up to make up for the added depth.
The next thing I would do is mist the tank using a water spray bottle and continue the misting of the entire tank bottom until water starts to pool in the lowest sections. I would then start planting any aquatic plants in there planned locations using planting tweezers to minimize disturbing the substrate from breaking down and forming fine particles. Lastly I would continue using the spray bottle to continue filling the tank until you can use a garden hose to trickle water slowly to fill the remainder of the tank without disturbing the bottom.
The tank water will more than likely be cloudy at first but will slowly clear with natural settling or if you are using some sort of mechanical filtration, slowly be filtered out. This cloudiness occurs with new Aquasoil too so don't be discouraged with the initial messy look. I hope this helps and good luck.
