Hi all! I’m wanting to add more live sand to my year old biocube because the sand bed has gotten pretty thin in spots from syphoning cyano and my goby moving it all around. Do I need to worry about a mini cycle or algae outbreak? Should I add a little at a time of the course of days or weeks or is it okay to add it all once? It’s a 32g biocube, and planning to add a 10lb bag. Maybe not all of it through. Thanks!
