Ok i'm setting up a new 55gal. I have many before and have always used the colored fish rocks you get at the LFS. This time i want to plant my tank and have fish. I plan on Plantin it a desent amount with plants. I also know I want to have kuhlis and some glofish i just like the way they look. I plan on haven some snails in there also. What i want to know is what a good way to go is on the substrate. I really like the look of sand and want to get away from fish pebbles. I seen in a few posts people say the use soil. So what i was thinking was going with about .5in of soil .25in of gravel or something of the like and 1.25in in sand to get a 2in substrate. What are some of your ideas i'm startin to go crazy over this.
