I did this about 15 times then dump into another pail and repeat for the next load.
Putting it in the tank is definitely an empty and start over plan. If you want to do it quickly you can put the sand in wet, fill tank to about half, plant and decorate then siphon off the cloudy water and refill VERY slowly. Even though you've removed most of the silty stuff there is always more to stir up.
I used 18Kg for a 30" x 12" tank to an average of 2" depth.
Okay my large tank is 36 by 20 by 12.5 how much should I use? I would also be filling my 36 by 19 by 12.5 as well. So I have between all my tanks 90 gallons to fill from 2.5 gals to 38 gals
