Saw a picture of a sump using matrix, and thought about converting my cube from sand to matrix/rock rubble or whatever.
I was thinking going bare-bottom, but it’s not going to be a reef tank so I’d like a substrate for looks, and feel like rock rubble would be easier to vacuum out gunk without sucking up sand (using attachments on a Home Depot Buckethead)
I won’t have any sand sifters...... so is there any obvious negatives to using rubble vs sand?
