210 G Move ASAP answer

[Diana]

You are getting different answers because everyone has different methods, many will work, you just have to choose one that fits your situation best. Are there corals involved? If not, I would fill the 210g with fresh water, get the pumps going and then add the salt and dechlor/heavy metal eliminator. It may take a few hours until the salt mixes and you can get an accurate salinity reading. If you have 65 gallons to add of old water, only mix up the difference.

Once the water is the correct salinity and temperature, pump about half of the drum water into the 210g. Then, drip the new tank water into the drum over the next hour. Once the drum is again full, add most of it back into the 210g. Wait a few minutes for the water to mix in the tank, then add the rock and fish(i reccomend you also drip the rock although i have not in the past and did not see any abnormal effects). Add the rest of the drum water.

This method worked fine for us many many times. As long as you get the salinity and temp fairly equivalent between what the fish are used to and what they are going into, they should be fine.
