    Default crushed lava rock as a substitute for bio rings?

    still in the planning stages of my 55g FW sump system. been thinking of bio filteration, with the cost of bio rings i dont think it would be in the budget, so i was thinking of crushing up some lava rocks into inch or so peices and using them for bio filteration. i think ill have 4"x12" of bio space, so i doubt that will hurt too much. what do you guys think?

    I don't see any reason why not. It would sorta be like live rock...just as porous and no coralline would ever get in it to clog the holes...
    If carbon holds bb, lava rock should be way better.

    Crushed lava rock will work just fine.
    When in doubt, do a water change.

    Yes it will work. No its not the best. IIRC lava rock has an OK surface area, but the large pores clog up with gunk, can be hard to clean, and it takes up a significant amount of space.

    Crushed terra cotta pots are the way to go IMO. I run them in every tank. Less surface area than the purpose made ceramics, but way more than lava rocks.

    Just my take on it. Lava rocks will probably be fine, but I would be curious how your nitrates look after about a year.
