I had a fifteen gallon that I started with live sand and life rock that I got from about three different people a few years ago. I had pineapple sponges, little feather dusters, tons of pods, and other cool little animal life. I would just sit in front of my tank and use a magnifying glass to look at the diversity for hours. This time I started with dry sand and dry rock and after a year the tank is not as fun for me. I already have enough rock in my display, should I buy some live rock and place it in my sump?
Thanks for any suggestions.
