I have purchased both LS and LR from here and the service/product was great. I agree w/Mr. Salty on the 40lbs of LS for your tank. And it is true that you should not rinse it before adding it... However, if you are adding the LR to an already established tank, you may want to cure it first. If you are setting up a new tank, just add it and it will cure in the tank and also help cycle it. Also remember not to let the LR dry out. If it dries completely, it will more than likely be dead. When I ordered my LR from here, the box broke open and leaked but the rock stayed damp because it was covered in newspaper. Hope I helped..
