I have deep sand bed and not a lot of space.
How deep is this sand bed? And how many lbs live rock? Sand shouldnt be able to actually cover 50% of your rock.
But to answer. The rock will still maintain its beneficial bacteria however it will do the job better of converting ammonia of the rock is subjected to flow. So you may need more live rock, depending.
