Hello all, I am new here and have read a lot of great things and there are so many awesome tank pics here! I am new to the planted tank and wanted to ask a question about fertilizers. I have chosen to go with the Seachem Flourish series which I have heard a lot about. Is this one of the better brands? I have the Excel for carbon and the Flourish supplement. Is it necessary to get anything more than this? Also do I still need CO2 injection with the liquid carbon? I am also using Eco-complete substrate. Thanks so much for the replies and help.
