OK so I've got some JBL Aqua basis plus substrate which I am going to mix with sand to make it go a bit further, now what should I use on top? I was originally going to use the sand on top of the JBL but someone on here has informed me that it will over time go underneath the JBL, so I want something that will sit on top, looks good and as I have Loaches and Cory's it has to be something they can dig around a bit in.
Any suggestions?
