Yeah, but how is that "same way"?
When I acclimated mine 4 months ago, it was successful and I wasn't even being too fancy. I sat the plastic bag on the water. Then 15 minutes later I added a cup of tank water in it.
15 minutes later, I removed half of the bag's water. Then replaced that same quantity with my tank water. 15 minutes later, I repeat the process. 15 minutes later I repeat the process again. Then I net out the snails (or whatever fish I bought) and let them in the tank. It may sound a bit too much work. But you have to realize that I was playing play station 2 in between the processes. So it wasn't much. It only took an hour. That's about 2 maps for me in SOCOM 2.
JG, I recently did a hyposalinity treatment on my tank because of ich from god knows where. It killed the snails. I took them out by net and....Wow, the stench spread all over my living room. It was the ultramagnus-bombardostink halitosis from hell!!
