I finally found a new tank for my fish after the oceanic popped a seam for the second time. I am going to take as much of their current water and keep it when I make the transfer. But the new tank is a few times bigger than the old one and I worry about the bb not being able to handle the new amount of water. I might fill a second tank with fish water so the bb can start to form in the rock and what not. I just don’t know how the best way to handle the transfer as far as the amount of new water
