If this goes as planned, (not likely) After I empty out my existing tank I will scrape off all the mulm growing on the sides and back to add to my new tank and under my UG filter. I can't wait to see what is growing under there and I will also be bringing whatever that stuff is. I will try to eliminate the larger bristle worms, the 2 foot ones with the antlers and Godzilla larvae. I will have to break off all my montipora and try to get most of the rest of the corals and sponges out. I am sure I will lose some, or maybe even all my corals as the lights may not be functioning correctly for a while as I build stuff. It all depends on if I can keep this house for a few days after I own that house. If I have to move out of here before that place is finished, I don't think the tank can stay running as I will have no place to transfer the livestock and rocks.
