Aquarium Advice Activist
Im going to be getting a 55g tank soon I am curious ive done live plants since I started and I know the l8hhting and im pretty sure qboit filtration. Im thinking about sand substrate. But I was curious, ive read threads about people having some type of layer underneath substrate for plant nutrients. I cant remember what it was called. Is this nessesary for larger planted tanks or just extra nutrients for plants. I currently use pps pro and excel for my carbon. Thoihht about diy carbon but im not even sure where to start any advice would be great.
