Darryl_V link said:NOt much for corals but for fish you have to be careful that the store you bought it from didnt have low SG holding tanks. Many stores keep there fish in very low SG to keep parasites off....unfortunately they often forget to mention that to customers. When this is the case it can take many hours to acclimate safely. Killed a few fish when I first got into the hobby because BA forgot to give me this information.
+1 to these. I use the drip method but instead of an air valve, I tie a knot in the tubing then loosen towards the end of the acclimation period to allow water to move faster and bring the temperature up closer to tank temp. I generally takes me 3-4 hours (or longer) to acclimate because of the decreased salinity of the water included with the new fish. I will also put an air line into the water in case the oxygen gets low due to the length of time I acclimate.pulpfiction1 link said:i personally use the drip method.i use tubing with an air valve in the middle to control the flow of water into the bucket,i first dump the bag and contents into a bucket then start the siphon,set the drip rate to what i feel is comfy at the moment then check in about an hour,if the water level has increased by about 3 times or more it should be good to go,with coral i use a dip after the process
