If its not to late ? then never rinse new aragonite sand all that small micron dust is what will add plenty of magnesium and strontium and Ca. and Carbonates to your tank. This is why many have a hard time to get any coralline growth. And then they turn around and buy the dust back in a bottle of water called purple up and aragomilk and the powder you just rinse is called agromite LOL. I have never rinsed it my self.. Also the same stuff in larger chunks is used in Calcium reactors .. Its your choice but to rinse it is to deprive your new tank of many needed elements. _________ Some of the world's greatest feats were accomplished by people not smart enough to know they were impossible (Doug Larson) |
