JoshCFI Posted August 2, 2007 Share Posted August 2, 2007 I replaced the bioballs in chamber 2 with LR. My question is should I leave the stock lid that goes on top of chamber two in place or remove it? Also what about the sponge in chamber 3. Should I remove it? Thanks Link to comment
Kirin1 Posted August 2, 2007 Share Posted August 2, 2007 Ditch the sponge, unless you want to change it every 3-5 days. Some people (like me) put chemical media in Ch3, but not necessarily where the sponge goes. If you can wedge a bag down in there it'll get good flow-through, but I for one can't get my big fat hands back there to get it out. I use Purigen and Phosban in media bags. I've seen many people use a bit of filter floss on top of that grate, basically using it as a media holder. Again, it needs frequent replacement. If you want mechanical filtration, check out this Biocube Filter Mod thread for a quick easy solution. Link to comment
