You can easily start with a sanded and establish the system, then slowly suck the sand out with water changes. I've done something similar and I still have some sand, but about half of what I did. That was is much easier 5hab going bare bottom from the start.My only issue now is debating if I maintain to be bare bottom or put on sand. I am still undecided on that part. Aesthetically I prefer with sand but vacuuming bare bottom of detritus is a no brainer. Hhhhhhmmmm dilema. Suggestion?
