Well, so far my tear down of my 125 gallon tank is coming along. I scrubbed all the rock free of algae. I vacuumed the live sand. I set some base rock aside for future use. I want more open space in the tank with caves and more room for my fish to swim. Over the weekend I am planning on removing the old sump, setting up the new sump with baffles, refugium and main pump/skimmer section. I am also going to setup my equipment connections to the inside cabinet of the sump area so that I don't have all the wires on the outside. So far my fish have survived the whole transition. I love living and learning!
