{"product_id":"juwel-cirax-bio-filter-media-standard","title":"Juwel Cirax Bio Filter Media","description":"\u003cp\u003eCirax is highly porous ceramic-based pellets, supplied ready to drop in complete with its own plastic basket. The pore structure gives filter bacteria far more surface to colonise than sponge alone, which makes it the long-life biological bed of the Bioflow system — fit it and largely leave it alone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIt takes a slot, it does not add one.\u003c\/strong\u003e Cirax occupies space in the lower insert that would otherwise hold a sponge, so in the smaller M chamber you are trading mechanical and aerobic capacity for surface area rather than adding to it. And because it is a bacteria bed, replacing it resets that colony — do it on its own, not in the same week you change the blue sponges.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere it goes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the top of the lower filter insert in a Bioflow M, L or XL.
