No ! This is the best way !!
1) Float the bag in the tank for 15 mintues
2) Put the fish in a bucket
3) get the airline tubing, make sure it drips 2 times a second
4) then let it sit in the water instead of watching in drip !!
-Do not drip because that changes the ph and can shock your fish and just ruin the acclimation!!
5)So let it sit in the water and after 30 minutes take some water out of the bucket so there's more new water from the tank
6) do this for no more than 1hour as 45 minutes
- too long of acclimation will also stress your fish
7)float the bag again for another 15 minutes because when the fish is in the bucket , the temperature changes again do get it to the same temperature again
8) check the salinity and make sure they match
9) never net your fish !! Freaks them out !!!
10) take most of the water out because during acclimation they poop and pee and I don't think you want that going into your tank , so take most of the water out until its a little bit of water and your fish and gently release him in to your tank without exposing him to air ,
11) leave the lights off for a good 4 hours and let him get used to the tank and tank mates , they will not be pleased if they are thrown in a new tank with bight lights and new fish everywhere !!
12) good luck and I know it's a long process but all of it makes sense and a lot of people do it the easy way out but , this is a very safe and smart way , my point is that , THE MORE CAREFUL YOU ARE WHEN YOU ACCLIMATE , THE LONGER YOUR FISH LIVES !!
