Filter Media

[tropicalshaun]

Hey all,

I have a quick question ...

I have had a Biorb in my room for a while now and am wanting to get a new tank for the living room, namely the juwel lido 120, my question is with regard to filtration. the Biorb uses a small filter with ceramic filter media in the base of the tank in place of gravel, would i be able to use the Biorb media in the new tank to act as a filtration method alongside the juwel filter? i want to use gravel in the tank and have the ceramic stuff on top in places, not all over as it does look quite nice aswell

I'm sure a member who knows these particular tanks and filtration systems will come along and be better helps, but in the meantime...

I think I recall from other posts that some of the biorbs use what basically amounts to an undergravel filter system, pullng water through the substrate and having good bacteria-philic ceramics on the substrate as the biofiltration.

Unless the new tank is equiped with a mechanism to pull water -through- the gravel, it is not an undergravel system and merely placing the previous biomedia on the substrate surface will not enable it to keep being a form of biofiltration. Biomedia (ceramics, bioballs, sponges) will not serve as an enhanced surface for bacterial biofilms unless they are part of a filter system that is pulling fresh water past them containing their food (ammonia, nitrite(NO2)) and other essential nutrients (oxygen, calcium, iron.)

Your old mature media from the biorb would, however, serve as an excellent "seed" if put into the new Lido filter system during its cycling period. Or the mature media could be put in a little internal filter to run simultaneously with the new filter.
