No substrate For those of you that are running tanks with no substrate do you notice some what I am guessing flaking of the rock work accumulating? I have virtually no bioload but every week at water change, there is an area that the flow pushes and dumps whatever it picks up. It is about a half to one teaspoon each week and is mostly particles that look like small pcs. of rock. Is it normal for live rock to shed? I also baste at water change and don't usually get much off the rocks into the water column. |
