I see some people rinse their soil before putting it in the tank. So this I tried that. Most of it floats and I also know people are sifting it out. Which for the most part would leave one without any soil. I am guessing the most effective way to do this is to simply take the soil back out in squeezing out the moisture and then put it in the tank and weigh it down with your sand and gravel.
In the "The Ecology of the Planted Aquarium" she doesn't rinse at all you just put the dirt in the tank add enough water to barely cover the dirt let it sit for a day then come back and cap it. Then fill your tank partly. Let it settle again. Do a small water change then add your filter heater and plants. Then next day you let the filter run to clear up the water. Then add fish.
Either way I can see this could be a mess. Does anyone have any pointers?
