Please Help with my snails and corals

[kenman999]

First I place the corals inside the bag floated it in my DT for 30 minutes. Then I place some water from the bag and coral inside the plastic container and place it in my tank. I got a bucket and placed some DT water in and located it to a high level. I started dripping it at a rate 2 drops per second. When the plastic container was full I threw away half of the water. Repeated for 2 hours, I placed the coral in my DT and threw the water away.
