Sorry but you need to get properly aquainted with your current partially cycled aquarium and have fish that are suited to it and get a few years fishkeeping under your belt before spending thousands on a massive aquarium
The big aquariums are a huge investment in time and finances....learn the craft on the smaller aquarium so that you avoid the same mistakes already made on that one before you start going larger.
To be honest I don’t think it’s your business my finances or what time I have.
I think you need to get out mate and see the world. Stop hanging around your computer.
