i'm getting ready to set up a 40 breeder for my 3 senegal bichirs, and i would like to use sand as the substrate. the last time i did this was about 10 years ago, and i remember that the sand got into the box filter, and royally screwed the impeller. has anyone else had this problem? i want to use an ehiem ecco canister. any comments or suggestions? what type of sand to use? how do live plants( anubias, bolbitas fern) fare in a sandy substrate?
