So I'm getting frustrated after seeing how clean a lot of nice reef tanks sand looks and I started wondering, am I missing something? I wouldn't say my substrate looks dirty by any means, but it definitely is not show tank status. Do these people just vacuum before snapping these amazing pictures? Has anyone used those battery powered substrate vacuums that recycle the water back into the tank after being run through a filter? Are they junk?
