I am going to be starting my 150 with dry rock (want to minimize contaminates) I am looking at the Pukani or the Reef Saver. I know the Pukani is more Puris then the reef saver but I think the reef saver will be easier to scape. Does anyone have any suggestions on which one I should go with? Also It will be a SPS dominate 150. I have heard people say that Pukani also tends to leach PO4 back into the system after a few years?
