I have built a few skimmers before and I want to try my hand at building a cone. I am looking for suggestions on a pump for it. My tank is a 210 with a 60 gallon sump, so 270 gallon total volume. It is a heavy stocked tank. I was thinking of a cone with about a 12" base 5-6" neck and around 25" tall. My first thoughts on a pump was a modified Laguna from MSX. Does anybody have any experience with this pump? Any other pumps worth looking into?
