Ok, so my RSM 250 has been running for 11 months now. I have had a small leak in the tank and Red Sea sent me a new tank to switch out the old one. I want to map this out and do it right. Can anyone with experience help me so I can avoid losing livestock. I have about 15 corals and 8 fish in the tank. I will have to move everything to a storage tank/container while I move the new tank in. I think I want to just replace the sand bed rather than reuse my live sand. Does anyone see any potential problems with a new tank and the bio filter. I will be resuing all of my live rock of course.
