Has anyone used Carib Sea Cichlid Mix Substrate (sand)in their tanks??
I am setting up a 300ltr tank and was wanting to try it as i have noticed that the coral sand i currently use irritates the fish's gills and i also wanted to go with a darker substrate anyway.
I just wanted to know if this actually does make a diffrence from using irritating coral sand?
Is there any other black coloured sand substrate that buffers your water which is good?
