purchase an over flow, along with the prefilter and a return pump.
fill the new tank with pre mixed saltwater. it should be fine if it isnt cycled. start the over flow and return pump.
now you have somewhere to keep your heater, run your chiller, protein skimmer, and you have more flow in your tank.
