Oceanic 82105 BioCube Original Replacement Filter Cartridges, 2-Pack

My aquarium eats one of these about every ten days. You can rinse/shake it out in a sink or bowl full of water drained from the aquarium but the cleaned filter will only last 3-4 days before clogging again. Couple of things to be aware of...a large part of your aquariums ability to remove waste revolves around beneficial bacteria growing in your filter. When you take the filter out, you remove a lot of organic waste from the ecosystem but you may also remove a lot of the bacteria that are clinging to the filter.

As such, when replacing the filter do not clean any other part of the filter assembly. Do that a week after changing the filter.

I also do keep the last "full" filter and after rinsing in drained water I tuck it on top of the filter mechanism under the door so it stays damp. When I do a water change I use that filter for a few hours after the change to catch all the junk that gets knocked loose in the water, then toss it and use a new one.

I've found that peeling a layer of the gauze medium back once it is clogged greatly extends the useful life.

I'll continue to buy these.

These are the required filters for my biocube 29 gallon saltwater tank. These filters clog pretty fast and do not last usally more than two weeks. The company I ordered the filters from are great. They shipped the items quickly and they had the best price.

Excellent product. I do think its a bit expensive as there are alternatives out there that do the job just as well, but this one is specifically designed for my aquarium so it fits a whole lot better :)
