My 40G is roughly 3 months old I'm going to add a 40G sump with new dry rock and sand (I just started soaking it in a Rubbermaid while I wait for the sump to arrive in a few days). the tank currently has livestock and corals. Am I running a risk by adding the sump if so what should I do to acclimate the sump to the main tank?
Thanks!!!!
