Hello all, first time poster here and hoping for some advice. I currently have a 90 gallon tank that has been stocked with various fish for about 2 years. I would like to upgrade to a 150 gallon tank and would like to know the easiest way to go about it. The equipment I have was all received used, so the tank, canister filter, lighting equipment and heater are all about 3 - 5 years old though they seem to still be in good working order. When I get the new tank I plan to change my substrate from rock to gravel. The fake plants, rocks, etc and other items inside the tank I plan to keep and perhaps just add some new ones to fill out the new tank. My questions are these: Do I need to let the new tank cycle if I plan to transfer a majority of my tanks current water into the new tank. If I get a new filter but use the current media within my old filter, is that acceptable? And any other suggestions to any questions I don't know to ask would be helpful as well. Thank you!!
