That is part of my long term plan. I was a minimum of a 300 gallon tank. And the refugium I had planned was always going to be equal to or greater than the tank itself. However I have to take my hobby a little slower now. My husband is not as on board as he used to be, which wasn’t much to begin with.@Lady of Babylon
When I moved into my dream house, I had been operating a marine aquarium for ten years, but always a 55G tank. I upgraded to a 150G tank which included oak cabinet stand but no sump. As the reefer addiction grew, I wound up with a 1500G remote refugium/growout system in my garage. Find a place to put a 150G Rubbermade tub. For your goals in this hobby, it will serve you well.
