How many bags do I need?
I am in the process of setting up an aquarium with the following dimension 24" x 18" wide and 16" tall. With the floor space how many bags of flourite do you think I need. I thought I could get by with one, but it doesn't look like it's going to be sufficient. I'd like to have a gentle slope from the back. My plan is for some drift wood and a few rocks, but nothing that would significantly displace the substrate.
I'll probably splurge on another bag of flourite, but do you think this is sufficient?
