"Works as expected."

The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. For my smaller fish tank I find that it is just enough. I have a Top Fin 10 power filter and these cartridges fit perfectly. Does the job and price was less or at least same as big retailers. Of course you will need to let the silicone cure before installing in water. Luckily I'm using powerheads and the weight of it helps hold it in place. Fun to modify your filter and clean tank as well.

CNZ CNZCBR2PK Final Thoughts

"Glad I bought 2."

It was nicely packaged and is a high quality filter material. I use two layers of floss before the water goes to and through my chemical media. I rinsed and reuse same pad again 3 times and trashed later. But a small simple rubber band fixed the issue quickly. Small amounts of these bubbles can also help oxygenate the water over time. It includes 12 mesh filter bags& 12 packets of charcoal. This is great for transporting aquarium life from location to location too.

"5 gallon tank."

Fun to modify your filter and clean tank as well. Don't restrict air-flow around them as they do get quite warm. It was nicely packaged and is a high quality filter material. Does the job and price was less or at least same as big retailers. Don't get anything smaller than 750VA as you don't want to overload them. Right now I am letting the filter work it's magic.

"Hand down the best."

If you have several aquariums, use separate UPS backups. Of course you will need to let the silicone cure before installing in water. Don't get anything smaller than 750VA as you don't want to overload them. The other tank is an old AIO retro tank I have with a media rack in it. The air stones, plastic tubing, and charcoal were provided which one would expect. It comes with carbon filters, and air stones. In 20 gallon and under sized tanks these start becoming feasible primary filters.

"Good product."

It's a pain in the butt to put together the directions don’t do it that well. I have used UG filters for many years. If you don't know much about this just google it. I will update more pictures later, once the water isnt cloudy. It was a struggle to keep the water clear before i got the goldfish. They are easy to clean but are very small. You can cap off the ones you don't want to use.

"Easy to handle."

The first piece does get a bit dirty and usually only lasts a week. Ignore all the noise about them being outdated they are a must-have buy it. I will update more pictures later, once the water isnt cloudy. I have a Top Fin 10 power filter and these cartridges fit perfectly. Of course you will need to let the silicone cure before installing in water. Within a matter of hours I now have a crystal clear tank with pristine water. We use this product to the extreme.

"Quiet and reliable."

The UG is certainly no exception to that. I had to take a blade and run it through all the slats because the factory doesnt q. I was having a problem with tiny fish getting sucked into the inlets. You will also need to replace their rechargeable batteries about every 2 years or so. I will keep using these and recommend them to anyone. The foam is not coarse as illustrated; it's finer and denser. We use this product to the extreme.

"It's amazing."

I purchased these for an aquarium at school. If you have a nano tank with filter these would be perfect for that setup. I can now afford to change all my filters at a fraction of the cost. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. Nitrates in small doses are not as harmful to the fish as Ammonia. You can cap off the ones you don't want to use. It comes with the filter bag, bag frame, and charcoal media all separate.

"They do the job well!"

The foam is not coarse as illustrated; it's finer and denser. Outside tank on deck with just a few fish. I just changed it today and the water is crystal clear-- no problems. I bought these because I was afraid my shrimp were getting sucked up in the filter. The box comes with super easy and clear instructions. Lets start with the amount of filter material you get. Tank is clean and all my new shrimp are still alive!

"The hole is smaller."

You can put power heads on the riser tubes to increase the flow through the filter. The first 3 pics are of my RR tank with sump. Better than branded media filters cartridges. The concentration of flow will mean faster clogging, lower flow and motor strain. Never use live rooting plants with UG filters. Fill with the supplied carbon and voila. You can run everything on battery backup sockets.

"They seem to be legit."

If you have several aquariums, use separate UPS backups. The first 3 pics are of my RR tank with sump. The other tank is an old AIO retro tank I have with a media rack in it. For obvious reasons, don't put them directly above or below a tank. I had to take a blade and run it through all the slats because the factory doesnt q. Especially if you have a take with shrimp or baby fish. These work great as pre filter sponge on my quiet flow 10.

"One more thing."

And provide a few low current areas in the tank for fish who are stressed to rest. I rinsed and reuse same pad again 3 times and trashed later. I have found you really have to scrub the outside to get everything cleaned out. I also suppose my measuring tape may be off, but I would not think so. The box comes with super easy and clear instructions. Cut slightly oversized, it seems very effective as a particulate filter. If you have a nano tank with filter these would be perfect for that setup.

"I bought the 6ft roll."

If you have a nano tank with filter these would be perfect for that setup. I was having a problem with tiny fish getting sucked into the inlets. Small amounts of these bubbles can also help oxygenate the water over time. Fun to modify your filter and clean tank as well. I end up cutting a small 2x3 inch square for each of my media baskets. This is a lot of filter pad for your money. You can run everything on battery backup sockets.

"Great product."

The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. But if you don't weekly vacuum it up, it will eventually clog the filter. Have been using this product for few month for my planted tank. Any floating debri will get caught in a sponge intake on the reverse power head kit. Don't restrict air-flow around them as they do get quite warm. Works well for my low flow Aquaclear 20. I have been using an Aquaclear 50 on a 20g long planted tank.

"Love this sponge filter."

7in, which is only about half the length of the unit. I even used some in my Fluval 206 canister filter on my freshwater tank. Plenty strong to support the rocks and gravel in my tank without sagging. Outside tank on deck with just a few fish. It made no sense why one was ten and the other was twenty. I end up cutting a small 2x3 inch square for each of my media baskets. Why not save some money to put towards more fish or supplies.

"You get what you pay for."

I end up cutting a small 2x3 inch square for each of my media baskets. These work great as pre filter sponge on my quiet flow 10. Lets start with the amount of filter material you get. I have always had an undergravel filter and my aquariums. It's a pain in the butt to put together the directions don’t do it that well. For obvious reasons, don't put them directly above or below a tank. For my smaller fish tank I find that it is just enough.
