What would be the best way to lay down sand up front and keep the gravel in the back?
If I do this, it'll be in a couple months when it warms up as pfs is no where to be found around here... Unless I order offline. Petco sand is just too expensive.
For those that wonder why I want to do such a thing.... I get bored with tanks quite easy. I love switching things up. I'd keep the front gravel in, just move it to the back.
Ultimately, I guess my question is what will hold the gravel back and separate it from sand so it doesn't mix?
