Im getting a 55 gallon for christmas, and originally planned to do my first saltwater aquarium (fowlr). But im going to hold off intel i master freshwater, and my spelling lol.But i want to advance in freshwater and do live plants. I was wondering it t5 ho was enough to do low tech /high tech im more high tech so they grow faster. but im not so sure on everthing. im thinking of doing sand as my substrate somthing that made specially for plants. Also i confuzed how ferts work and if i neeed them or, how to use them. So overall i need to if t5 ho is good lighting and how to have a high tech setup,also how to use ferts. and how i know if i even need to use them. so i need to know about everthing in general, and if i need co2 injections and how and why. i think i asked my all of questions. THERES ALOT. thanks! and if u have need any more info just ask ill leave a reply.
