Aquarium Advice Activist
So as most of you know I recently started a 120 gallon Cichlid tank. Im used to maintaining smaller ones (40 & a 55) . I have my tank overstocked as advised and over filtered. For the first two weeks and prob will continue I have changed 25% of my water twice a week. Ill prob end up doing 50 % at least once a month. This tank is two feet tall and loaded with rock work. My question is how thouroughly and often do you guys vaccum your sand? Its obviously very difficult to get to it all . In my 55 I usually thouroughly vacuum 25% of it each week but there arent 10 & 20pd rocks to move and replace.
