Hi guys, I'm wondering if I can add the same brand of live sand that I used to start my tank with originally. I just want to add about 5lbs of more sand in because I got a Watchman and pistol shrimp pair and the shrimp has stolen sand from everywhere lol and I don't want it to get to a point where I see spots of bare bottom tank.Hes making huge mounds everywhere.Please let me know if this is "allowed" or a bad idea. Also if you know any tricks to get the new sand in without making the tank too cloudy. I used Carib sea live sand in a bag the larger crushed coral sand.
