I currently have a 20g AIO running and I am slightly upgrading to 40b with a 40b sump. Plumbing everything out now and looking to be up and running by the end of the weekend. However the wife has laid down the law and said no to both systems running, it is a condo to be fair. When everything is up can I just transfer everything over to the new system? Only have 20lbs of LR and will have about 50lbs in the new system between the sump and DT. How bad can this end up being?
