Sure can't see the need for a device as described on the link that does nor work as a simple piece of air line tube with a knot works just fine.....Just last night the lfs here got in a huge shipment of fish while I was there, and they have lengths of air line with a piece of hard rtype airline bent into a U on the one end. They use these to drip acclimate the new critters. They place buckets in front of every tank thats getting a new critter added, submerge the airline and then hang it so the U shape is on the tanks lip, water thats in the airline starts dripping out and starts up a syphon, and they tie a knot to adjust flow.......I don;t think saltwate ris gona hurt yu anyhow, odds are you probably put worse in your mouth over the coarse of a day out in rthw work force or shopping or around the house.
