Hello and welcome to TPT!
There is so much information here that I learn something just about everyday, and if I didn't learn anything that's probably because I just didn't read enough. My suggestion for you getting into the hobby is this, decide how much work you want to put into the tank, do you simply want an aquarium to oggle or are you lookin for a hobby? If you want something to oggle and not have to put much work into it I would suggest going with a low tech setup. But if you are looking for a hobby jump in and start with a high-tech setup. Co2 and good quality dry fertilizers are the best money spent on any of the aquarium stuff I've bought in the past.
