hi , i have seen people say in marie setups that the live rocl that you put in the tanks acts has a natraul filter media so all you need is power heads and live rock.....
could this be done with lava rock?
im hoping to set a tang cichlid tank up and thought i would use lava rock as deco and possible filter media and just have a power head to move the water ( so no need for a canister or internal filter), would the bacteria grow on and in the rock ?
thought would be much apprciated
