Every single one of the 24 HOB or in-tank filters in my house is stuffed to the gills (pun intended) with these. I rinse them in warm water, then use black pantyhose from the dollar store to make little pouches tied at top and bottom, then pack out every filter with the pouches. When you use these, you don't have to keep the bristled plastic inserts that come with the filter; removing them will give you more room for these rings. You also don't have to use any sort of pouches -- you can actually just cram them in there however they will fit. When I start a new tank, or if a friend wants to start a tank, I steal a pouch or three from other filters for the new one, and *poof* instant-cycle.

Three of my tanks are overstuffed with guppies (my daughter brought home three, and now we have 100, mostly juveniles), who are very messy fish for their size, and even those tanks have thriving nitrogen cycles. They are cheap, they are effective, and they never need replacing. The only reason I've deducted a star is because, as mentioned, lots of them are two stuck together, which makes it harder to smoosh the pouches down into the filter sometimes. It's not enough of a big deal for me to even consider switching to something else. … more

Pretty typical bio rings, nothing special about them, they'll get the job done and they are a really good price for how many you get. Some of them were stuck together but that's not really a big deal to me.

Can pack alot into the filter, but their not very porous and a lot of them were still stuck together. Spend the few extra bucks on the fluval rings.

Ceramic rings are very porous and with the hole in the middle allows for more area for good bacteria to grow.
