Looking for Advice on Tank Transfer

[DKoKoMan]

Canreefers,

I’m looking for advice from people who have transferred their tank in to another system (fish, corals, inverts etc.). Any tips or tricks to reduce the amount of stress on the livestock and keep loss to a minimum. I will be moving my 150g in to a new 305g system once it is finished being built.

I plan on transferring as much of the water from my current tank in to the new one. I will be replacing the sandbed with new live Argonite sand from Carib Sea (don’t want to spend time washing the current sand bed). All the LR from the system will be transferred over as well. I have mini colonies on a lot of the LR that I am going to try not to break in the process. New SW will be added to make up the remaining water volume in the new system (hope it will be around no more then 50% WC).

I transferred my 75g in to the 150g once before and it went... well it went not so well. I lost majority of my corals and a bunch of my fish. I’m not sure if it was because the cloudy tank from the sand, the stress, the new rock or whatever else.

Looking for any tips that worked well in your experience. My wife and I are excited for the new system but are also dreading this transfer. Thanks for all the help!
