I have had a 105 gallon tank running successfully for over 3 years and I have finally completed the setup of my new 215 gallon aquarium. I have a lot of coral in my 105 and I want to move it to the larger tank. My question is would you try the insta tank method and move everything at once or would you take a slower approach. I feel like my other aquarium didn’t support acros for a year so I am hesitant to wait that long but nervous about killing lots of coral. Anyone with good experiences and advice?
