I'm slowly building a mixed reef system, corals to come soon. I'm looking for a good sand sifter to keep the sand surface stirred. I currently have 2 jawfish but they only keep a small area of my 245 DT mixed. Besides that I have a std CUC but they can not keep up with the brown lgea that grows on the surface of the sand - only a small amount but still a weekly attack point during WC. Any advise would be very helpful.
