 flow and sand
i was wondering, i am setting up a 120g tank, i would like to know how much water flow is good enough for this system, i currently planning on usig a mag 9.5 as a return, but iwant soemthing else more powerful, let me know. SO i was wondering about putting a dsb in the sump or should i use 100% clay for the fuge? can i keep the frags in there? or do i have to have a deep sand bed in the dsb? i will have around 4-5 dsb in my display.
