As a noobie when I got my 120 I had no idea what I did not know but after 15 months or so with it I am ready for a bigger tank with more possibilities. In the interest of full disclosure I’ll say that there’s no way I would ever pay thousands on just a tank but now I hear the advise my mom used to tell me all the time: “lo barato resulta caro” loosely translated “cheap **** will get expensive”. Enter the 180 “upgrade”.
