It is very difficult for newbies such as myself to design out tanks or areas of tanks when we have no idea "how close" together we need to plant Plant A to get coverage.
For instance, I just bought 10 plants yet I have no idea if those plants will take up all the space I have, 25%, 50%. Don't have a clue.
Is there a design or planting sticky tutorial that I can read? I'm to old to learn things the hard way, I could drop any day.
