Hello. i have set up a new sw tank. Was just wondering how oftern i should clean out the gravel/sand. Its a small nano tank and only has 2 small gobies in. Also anyone got any links to one of those gravel cleaners (the type were the tube has a cup type thing on the end which sucks the gravel and sand up a few inches then drops is but takes away the dirt)
not sure if that was explained well but im sureyou get the idea.
Cheers.
Paul
