I was told that if you have enough live rock & a thick sand bed then you don't need a filter. Is this true? So how much LR is enough to not need a filter for my 55 gal? I only planned on purchasing 1 - 45 lb box. Would you still need the filter at 1st until the rock was fully cured & then take it out?
