Hi, I’m looking to upgrade my 20gal in to a 45gal and I am going to use all the sand and probably have to add a little more, I’m using same rock and I’m going to transfer the water into it as well I also have small frag rocks in my big tanks refusion that I’ll toss in the filtration plus some bio balls that have been sitting in the sump for a while too. would I need to move my fish and coral into the tank? just in case it spikes or would it be fine.
