When I was setting up my 150, I purchased maybe 10 bags of new sand. I went to Home Depot and got
sediment filters to run in the reactor. I used them along with manually stirring up the sand instead of putting the sand in a bucket and running a hose into it to get rid of all of the dust.
This is just after setting the tank up. You can see the Maxijet feed pump on the right side along with the white tubing that leads to the reactor. I wouldn't suggest them for long term use, but I think they worked great for getting the junk out of the water quickly.
