For future acclimations, Its best to do a drip, you can put them all in a bucket and the use an airline tube to drip the tank water into it, about 5:1 ratio, and for fish about 15-30minutes tops, and snails IME 30++ I did my turbos for 1 1/2 hours. but thats just me! drip acclimation is a great method and I thank many users on here for reminding me of that
