How to clean dry or used sand for your reef
Dry sand can be full of dust and cloud your tank for days. Used sand can be full of detritus and bad stuff that you probably don’t want to add into your tank. If you are using either of theses sands its best to give them a real good rinse prior to use. The easiest way is to pour your sand into a 5g bucket and push the garden hose all the way down to the bottom. Turn your hose on full and let the water work its way and and bring the little particles with it. You can swish it around and mix it up or just let it run. I any take a good 20 minutes with the water running so you mind as well do it in the middle of your lawn so it gets a good watering!
Once the water runs clear you will want to ensue the sand is fully dried prior to adding to your tank.
Spread your sand out on a tarp and let it bask in the sun until dry and your good to go.
