One of the most crucial parts of maintaining your aquarium and keeping it healthy is the beneficial bacteria that live in your filter. This nitrifying bacteria consumes harmful ammonia and nitrite and converts it into mostly harmless nitrate. In order to work efficiently, the bacteria needs good water flow, plenty of oxygen, and surface area to grow on.
Aquariums traditionally use gravel, lava rock, or ceramic disks like these as well as sponges for good bacteria to colonize. Sponges provide a ton of surface area making them the perfect breeding ground for these bacteria to grow.
Sponge filter foam is rated by the number of pores per inch of foam. The lower the PPI, the larger the holes. 20 PPI has 20 large holes in a square inch while 40 PPI has 40 smaller holes in the same area. This means the lower number of PPI won’t catch as much debris and therefore will clog slower. A sponge with a higher number of pores is great for filtering out tinier particles and polishing your water.
When using the sponge as biological media you need to keep it free from getting clogged with debris. Simply use a layer of mechanical filter in front, like our FilterFirst Premium filter pad to keep your sponge clean, allowing it to work efficiently.
In addition to our sponge being great for biological filter media, it can also be used as a mechanical filter to catch debris floating in your aquarium water. Keep your water quality high by rinsing the sponge regularly to get rid of all that trapped gunk!
The sponge can be cut to fit virtually any space in any filter. To start, mark a template on some cardboard or foam board. For this video, we’re using a canister filter and our pad needs to fit inside this tray. Once it’s traced out, cut out your template and trim it if necessary. Don’t worry about getting it perfect - you can squish the filter material a little bit to make it fit. Hold onto this template to make it quick and easy to cut new filters when you need them.
The sponges are made to last, but if they do get damaged they’re easy to replace! When the sponge gets clogged, you can gently rinse the sponge. If you’re using the sponge as biological media you must avoid using chlorinated tap water, as this will kill all the good bacteria! Rinse the sponge using dechlorinated tap water or water from the aquarium.
