Sorry. I forgot the drip acclimation thing. There is a description of it in our blog section, but you may have to go through several pages to find it. Basically, you put the new fish and their water into a clean bucket then slowly drip aquarium water into it. Regular plastic buckets hold about 2.5 gallons, and you take about an hour to drip in a gallon or two. The dripper is just a piece of air hose with a valve on the end; you start a syphon and adjust the water flow with the valve. I've lost fish introduced by the old floating bag method but have never lost one using the drip method. Check the blog for more details.
