I know these newb posts are really annoying, but i'm feeling pretty lost, and the more i read the more confused i get. I have a 10 gallon setup with a t8 15w light. My goal is to learn enough about aquatic plants to have a nice full carpet of dwarf hairgrass in my tank along with some wisteria/javafern, maybe some other low light plants. I'm in the process of making a diy co2 generator, and I know what kind of substrate i should get. Fertalizers kind of intimidate me, and i'd like to make sure my water parameters are safe for my dwarf puffer. Is there like one fertalizer product that would effectively fertalize my tank for my plants, or would i have to understand everything there is to fertalizers? I'm thinking of upgrading my lights, because i only have 1.5 wpg, and i read that dwarf hairgrass needs better lighting for a full carpet effect.
Any help on explaining fertalization would be greatly appreciated, I have no idea on where to start.
