The "cut and dump" method as we call it seems to be the common way to acclimate. This method works until it doesn't work anymore.
We have another way to acclimate your fish and critters---Drip Acclimation! You need drip line or an acclimation line and a bucket/large container/pitcher. One end of the drip line will go into your tank (anchored or clipped down) and then you are going to create a siphon on the opposite side that will hang in your bucket. You will create a knot in the drip line, a few inches from where the water is coming out, the tighter the knot--the slower the drip. You are looking for a consistent drip not a stream. Make sure the drip is actually making its way into the bucket and not the floor! After you have started your drip line, cut open your new critters and place them and their water into the bucket.

We want to make sure your new freshwater fish do not go into shock when adding them to your tank. Ph is what we are looking to match while acclimating. While your new fish are acclimating in the bucket with your tank water being dripped in, check the pH of your tank and the pH of the bucket. Once they match, the fish can be netted out and go in!!! This process should take no less than 30mins. We treat our freshwater main fish system with Prazipro and Paraguard from Seachem. DO NOT USE COMMERCIAL MAIN FISH SYSTEM WATER IN YOUR AQUARIUM.
Southern Aquatics personally DOES NOT use copper in our fish system. However, we do keep the fish system between 1.018-1.020 salinity and treat with Paraguard from Seachem. After trial and error over the past year, this method works for us to provide you with the healthiest fish. Which is why we stress the long acclimation period. Acclimating fish from 1.018 up to 1.025 should take no less than 3 hours. When drip acclimating saltwater fish we are concerned about the salinity. Once the salinity in the bucket matches the salinity in your tank they are good to be netted out and put into your tank!
