I don't see any point in starting out your cycle until you have a strong game plan, and that requires some idea of what you kind of tank you want.
Let me explain further. If you are wanting a reef tank, then LR
is a must. If you start your fishless cycle now, then when your LR
order comes in, it will require your to either cure it separately, (which is an added cost and hassle), or will just endup recycling your tank again.
I agree with the others who said read as much as possible. It will however clarify some questions you have but will also bring up new concerns that you hadn't even thought of. This process, however, will give you all the info needed to start a succesful tank and take your first steps in the right direction.
I also think it's wise to start making your livestock wish list now, that way you can start researching the animals as well and avoid the pitfalls of buying things on a whim and finding out after that they just are't meant for your tank.
