Has anybody used Dupla bioballs? They're supposed to have "21.5 sq. feet of surface area in every gallon" packed with bioballs. I was thinking they might be useful in a canister filter to provide biological filtration there. Anybody kept sea apples in their salt water tank? Aren't these related to sea cucumbers which can sometimes heave up their guts fowling the water? or is this just another myth? -- Ken Dalka (Bell Labs) ihnp4!ihlpg!dalka IE 2F-518 (312) 416-7437
