    Wetty - why would you want to use bio-balls?

    No - you don't need crushed coral or bio-balls.....

    ONLY the DSB is/should be 100% for long-term filtration.... This is the absolute best....

    How would you set a DSB with particles that size, you need to create anaerobic conditions for a DSB to function.
