The problem is my current tank is 180 gallons. There is no room to connect a second tank. My plan is to place a new tank in the kitchen, but she has other plan.
I bought a used 180g acrylic tank with scratches. Spend a full day buffing with 300 grid sand for deep scratch and 1000 for minor scratches. Fished with nuvo 1,2 and 3. It is doable. Make sure you wet sand it with rodi water.
