mathobes Posted March 24, 2010 Share Posted March 24, 2010 Hey all, today my girlfriend bought a tank and filter for a community setup. It is an aquaone clearview hang on filter. It has the foam pad with activated carbon in one cartridge an their is also a second cartridge that seems to be just a gridded piece of plastic that claims it enhances bio filtration and optimises colonization of nitrifying bacteria. But it's just a bit of black plastic? I've never seen one before and it seems odd that they would claim a bit of plastic to do these things. Has anyone seen one of these before and can explain how a bit of plastic is bio filtration? Thanks Link to comment Share on other sites More sharing options...
malrift Posted March 24, 2010 Share Posted March 24, 2010 The grid gives it surface area for bacteria to grow on. Basically if it is correct the surface area in a grid should be more than a straight bit of material. Bacteria will grow on any surface in the tank. The grid just allows more area for the water to pass over and allowing the bacteria to filter more water. Kind of. Link to comment Share on other sites More sharing options...
mathobes Posted March 24, 2010 Author Share Posted March 24, 2010 So it's kind of just a non neccesary attatchment. They made it sound like that the cartridge itself was a bio filter Link to comment Share on other sites More sharing options...
dogboy Posted March 28, 2010 Share Posted March 28, 2010 sounds like a flattened bio ball Link to comment Share on other sites More sharing options...
shelly Posted March 28, 2010 Share Posted March 28, 2010 yes it is the same as a bio ball, very good place for good bacteria to thrive. Link to comment Share on other sites More sharing options...
