"5 minutes of work!"

The filter material itself is good quality material too that doesn't break open. Customizable in terms of media used. Small amounts of these bubbles can also help oxygenate the water over time. Fish that are constantly swimming hard will tire and die from stress. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. This is great for transporting aquarium life from location to location too.

Fluval A480A1 Final Thoughts

"I had one break easily."

It comes with the filter bag, bag frame, and charcoal media all separate. Fun to modify your filter and clean tank as well. But by two weeks, the output did drop. Even its quite costly, but it last long. I've definitely noticed a difference in my water quality. Don't get anything smaller than 750VA as you don't want to overload them. The UG is certainly no exception to that.

"I use the APC brand."

I will be using Koral Filter material from now on. Don't restrict air-flow around them as they do get quite warm. The first 3 pics are of my RR tank with sump. You can cap off the ones you don't want to use. I've definitely noticed a difference in my water quality. Of course you will need to let the silicone cure before installing in water. I end up cutting a small 2x3 inch square for each of my media baskets.

"They work very well."

I have used UG filters for many years. You will also need to replace their rechargeable batteries about every 2 years or so. It comes with the filter bag, bag frame, and charcoal media all separate. I will always buy these here on Amazon for the price savings. It was a struggle to keep the water clear before i got the goldfish. I have been using an Aquaclear 50 on a 20g long planted tank. Every tank should have intake sponges.

"Go with the Whisper."

In 20 gallon and under sized tanks these start becoming feasible primary filters. We rinse the filters 2x a day and they remain in continuous 24 hour operation. If you have a nano tank with filter these would be perfect for that setup. Tank is clean and all my new shrimp are still alive! I have always had an undergravel filter and my aquariums. Keep your stocking of creatures low. Still, the price is of course fine at 4 for 6.

"Great product."

I changed water 4 days in a row and still cloudy. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. The first piece does get a bit dirty and usually only lasts a week. Outside tank on deck with just a few fish. I bought these to put over the inlet to the filters in my aquariums. I changed water 4 days in a row and still cloudy. Never use live rooting plants with UG filters.

Fluval A1490 First Impressions

"This was a great deal."

Works well for my low flow Aquaclear 20. The foam is not coarse as illustrated; it's finer and denser. 7in, which is only about half the length of the unit. I have a Top Fin 10 power filter and these cartridges fit perfectly. I've definitely noticed a difference in my water quality. I purchased these for an aquarium at school. I purchased this bulk filter media for a Fluval 207 canister filter.

Fluval A1490 Final Thoughts

"I would buy it again."

The air stones, plastic tubing, and charcoal were provided which one would expect. The other tank is an old AIO retro tank I have with a media rack in it. Within a matter of hours I now have a crystal clear tank with pristine water. It was easy to assemble and very effective! Don't get anything smaller than 750VA as you don't want to overload them. I will update more pictures later, once the water isnt cloudy. Better than branded media filters cartridges.

"Great product."

I was having a problem with tiny fish getting sucked into the inlets. In 20 gallon and under sized tanks these start becoming feasible primary filters. The first piece does get a bit dirty and usually only lasts a week. So stock your tanks a few fish at a time. I rinsed and reuse same pad again 3 times and trashed later. You get what you pay for but i had to work on it a lot. I missed it in my opinion these filters are a must have.

"5 gallon enchant tank."

I end up cutting a small 2x3 inch square for each of my media baskets. Don't shut it off for more than a few minutes at a time. Don't get anything smaller than 750VA as you don't want to overload them. It was nicely packaged and is a high quality filter material. Make sure to select the Medium size from Tetra. Just be super careful with the tubes! But a small simple rubber band fixed the issue quickly.

Fluval A1378A1 First Impressions

"5 gallon tank."

The injection molding for the plastics leave a lot to be desired. Luckily I'm using powerheads and the weight of it helps hold it in place. It was easy to assemble and very effective! And provide a few low current areas in the tank for fish who are stressed to rest. I can now afford to change all my filters at a fraction of the cost. The air stones, plastic tubing, and charcoal were provided which one would expect. I bought these because I was afraid my shrimp were getting sucked up in the filter.

"5 minutes of work!"

These work great as pre filter sponge on my quiet flow 10. I also suppose my measuring tape may be off, but I would not think so. This filter system doesn't come with everything to you need. I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter. Don't believe people who tell you they are dangerous for your tank.

"Hope this helps!"

Customizable in terms of media used. I double the size and fold them and put the bagged carbon between the layers. Better than branded media filters cartridges. Don't shut it off for more than a few minutes at a time. Fish that are constantly swimming hard will tire and die from stress. It's also a pretty substantial roll. I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter.

"5 gallon tank."

I bought these to put over the inlet to the filters in my aquariums. This improves flow and prolongs time between cleaning. These have prevented my original problem. We use this product to the extreme. Fun to modify your filter and clean tank as well. Does the job and price was less or at least same as big retailers. This filter system doesn't come with everything to you need.

User Ratings: 86 3

Fluval HGA449NET First Impressions

"Pretty good."

We rinse the filters 2x a day and they remain in continuous 24 hour operation. For obvious reasons, don't put them directly above or below a tank. Any floating debri will get caught in a sponge intake on the reverse power head kit. They are easy to clean but are very small. It's also a pretty substantial roll. It was nicely packaged and is a high quality filter material. Did all of mine The same, never ripped a one and they all fit like a glove.

  • Fluval 407 Performance Canister Filter 120Vac, 60Hz, 10.8 LB
  • The 07 series features new engineering solutions that work cohesively to produce a fluent operation that is up to 25% quieter than before
  • Depending on the model selected, the 07 Series generates between 145 - 383 US Gal/h (550-1, 450 L/h) of constant pumping power and pressure that endures over time
  • 07 filters are big on power, yet small on energy consumption. The 107 and 207 models, for example, draw as little as 10 watts of electrical energy, which is EQUIVALENT TO A SINGLE HOUSEHOLD LED LIGHTBULB!

"I'm a client for life."

I use two layers of floss before the water goes to and through my chemical media. Have been using this product for few month for my planted tank. Also work great as filler for canisters and other filters. Keep your stocking of creatures low. They do feel a little thin but we'll see how they hold up over time. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. We operate a saltwater bait store, dealing in live shrimp and bull minnows.

Work perfect on my shrimp tank to keep them out of the filter. Don't restrict air-flow around them as they do get quite warm. Right now I am letting the filter work it's magic. I have been buying these bags for years. I also suppose my measuring tape may be off, but I would not think so. Fun to modify your filter and clean tank as well. Plenty strong to support the rocks and gravel in my tank without sagging.

"I use the APC brand."

Ignore all the noise about them being outdated they are a must-have buy it. I was having a problem with tiny fish getting sucked into the inlets. Make sure to select the Medium size from Tetra. It eventually begins to decompose into ammonia which is harmful to your fish. I changed water 4 days in a row and still cloudy. The UG is certainly no exception to that. Just be careful punching out the plastic.
