So I have been bouncing around the idea of changing my sand bed I originally started the tank with a fine substrate. However I'm getting kind of sick of constantly needing to clean the Rock due to the occasional sandstorm I did not want to lose the beneficial bacteria that has grown in the sand bed which is a few years old now and I just hate to think about getting rid of it. So I was thinking of taking the sanded out and placing it in my sump thus creating roughly a 4 inch DSB in the middle chamber of my sump my sump consist of a 40 gallon breeder the middle chamber is probably 13 inches long. So I guess I'm just looking for some input from fellow reefers as to the pros and cons of this .
