You are on the right track! You remind me of myself at the beginning of this year starting my 55 gallon. If you read alot of threads on here and ask alot of questions, you will learn alot in a short period of time. the one suggestion I would make is to get some ferts to sart dosing with. Your plants will need the micros & macros or they will soon start to get holes in the leaves and look ratty. Look at the sticky I believe under water parameters about dosing. very helpful!
Nice start! Also, Welcome to PT
