"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.

2. Fluval Output Nozzle for FX5 High Performance Canister Filter

Fluval A20226 First Impressions

"High quality."

I don't advise using a UG filter as the only filtration source in large tanks. I have used UG filters for many years. This filter system doesn't come with everything to you need. I purchased this bulk filter media for a Fluval 207 canister filter. I had to take a blade and run it through all the slats because the factory doesnt q. But if you don't weekly vacuum it up, it will eventually clog the filter. But a small simple rubber band fixed the issue quickly.

Fluval A20226 Final Thoughts

"Really good stuff."

We rinse the filters 2x a day and they remain in continuous 24 hour operation. I bought these because I was afraid my shrimp were getting sucked up in the filter. The best part about these in my opinion, is the price. But if you don't weekly vacuum it up, it will eventually clog the filter. Don't shut it off for more than a few minutes at a time. Don't restrict air-flow around them as they do get quite warm. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge.

Works well for my low flow Aquaclear 20. The first 3 pics are of my RR tank with sump. I replace my filter material in my IM Nuvo 20 reef tank every week. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. I purchased this bulk filter media for a Fluval 207 canister filter. I purchased these for an aquarium at school. Fill with the supplied carbon and voila.

"It's amazing."

Have been using this product for few month for my planted tank. Ignore all the noise about them being outdated they are a must-have buy it. It was exactly what I needed and fit beautifully. This improves flow and prolongs time between cleaning. I will be using Koral Filter material from now on. I will update more pictures later, once the water isnt cloudy. Keep your stocking of creatures low.

"Thank you, Marineland!"

If you have several aquariums, use separate UPS backups. Does the job and price was less or at least same as big retailers. But by two weeks, the output did drop. So stock your tanks a few fish at a time. You can run everything on battery backup sockets. And provide a few low current areas in the tank for fish who are stressed to rest. I even used some in my Fluval 206 canister filter on my freshwater tank.

"Nada, zilch, nugga."

The concentration of flow will mean faster clogging, lower flow and motor strain. Nitrates in small doses are not as harmful to the fish as Ammonia. Small amounts of these bubbles can also help oxygenate the water over time. Stop buying those expensive filters, buy this and make your own. I have been buying these bags for years. I have always had an undergravel filter and my aquariums. Nitrates in small doses are not as harmful to the fish as Ammonia.

"They seem to be legit."

Don't get anything smaller than 750VA as you don't want to overload them. We use this product to the extreme. It comes with carbon filters, and air stones. Right now I am letting the filter work it's magic. 7in, which is only about half the length of the unit. I purchased this bulk filter media for a Fluval 207 canister filter. The main part is cleaning, that I need to find out.

"5 gallon enchant tank."

Replace prefilter on pump inlet while filter is running. Fill with the supplied carbon and voila. We use this product to the extreme. It was nicely packaged and is a high quality filter material. I was having a problem with tiny fish getting sucked into the inlets. I had to take a blade and run it through all the slats because the factory doesnt q. I keep tubes of clear silicone sealer around.

"Works well."

The main part is cleaning, that I need to find out. I can now afford to change all my filters at a fraction of the cost. The more you overpopulate your tank, the more frequently you'll have to do this. The filters fit fine and I was happy to see that some carbon packs were included. We use this product to the extreme. It made no sense why one was ten and the other was twenty. Nitrates in small doses are not as harmful to the fish as Ammonia.

Does the job and price was less or at least same as big retailers. I just changed it today and the water is crystal clear-- no problems. Because they are the smart thing to do when you keep aquariums. I have been buying these bags for years. I use this in my filter for aquarium 55 gal. Make sure to select the Medium size from Tetra. You will also need to replace their rechargeable batteries about every 2 years or so.

"Good quality."

Plenty strong to support the rocks and gravel in my tank without sagging. Just be super careful with the tubes! It made no sense why one was ten and the other was twenty. You can run everything on battery backup sockets. The first piece does get a bit dirty and usually only lasts a week. I change my filters once a month, so the 12 pack lasts me a year! I replace my filter material in my IM Nuvo 20 reef tank every week.

"They work very well."

Fill with the supplied carbon and voila. Don't believe people who tell you they are dangerous for your tank. Fish that are constantly swimming hard will tire and die from stress. In 20 gallon and under sized tanks these start becoming feasible primary filters. It was exactly what I needed and fit beautifully. They are easy to clean but are very small. If you don't know much about this just google it.
