"Good price."

Of course you will need to let the silicone cure before installing in water. I've definitely noticed a difference in my water quality. The more you overpopulate your tank, the more frequently you'll have to do this. I will be using Koral Filter material from now on. If you don't know much about this just google it. Tank is clean and all my new shrimp are still alive! I keep tubes of clear silicone sealer around.

Aquatic Experts Final Thoughts

"Nada, zilch, nugga."

Don't restrict air-flow around them as they do get quite warm. Nitrates in small doses are not as harmful to the fish as Ammonia. You can also buy solutions that have the bacteria in them to also get started faster. I keep tubes of clear silicone sealer around. The UG is certainly no exception to that. Lets start with the amount of filter material you get. I just changed it today and the water is crystal clear-- no problems.

"Fits just right."

Lets start with the amount of filter material you get. I have a Top Fin 10 power filter and these cartridges fit perfectly. I took off two points because the pictures are misleading. Of course you will need to let the silicone cure before installing in water. I bought these to put over the inlet to the filters in my aquariums. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. Fun to modify your filter and clean tank as well.

Aquatic Experts Final Thoughts

"Really good stuff."

I have used UG filters for many years. The injection molding for the plastics leave a lot to be desired. Because they are the smart thing to do when you keep aquariums. I had to take a blade and run it through all the slats because the factory doesnt q. Particles fall off into the aquarium when you take them off to clean them. I change my filters once a month, so the 12 pack lasts me a year! The air stones, plastic tubing, and charcoal were provided which one would expect.

"Pretty good."

Right now I am letting the filter work it's magic. The injection molding for the plastics leave a lot to be desired. They are easy to clean but are very small. If you have several aquariums, use separate UPS backups. It eventually begins to decompose into ammonia which is harmful to your fish. For obvious reasons, don't put them directly above or below a tank. It works okay for now but I hope it does not mess up my filter in the long run.

  • Aquarium Mesh Media Filter Bags - High Flow - with Drawstrings for Activated Carbon - Reusable Fish Tank Charcoal Filter Bag - Aquatic Bags for Fresh or Saltwater Tanks
  • UNIVERSAL FILTER MEDIA BAG – Optimal for Activated Carbon (Carbon Sold Separately)!

"Works great."

7in, which is only about half the length of the unit. If you're looking for new filters, go with these. You can also buy solutions that have the bacteria in them to also get started faster. Stop buying those expensive filters, buy this and make your own. You will also need to replace their rechargeable batteries about every 2 years or so. If you have a nano tank with filter these would be perfect for that setup. I have a Top Fin 10 power filter and these cartridges fit perfectly.

I will always buy these here on Amazon for the price savings. I just changed it today and the water is crystal clear-- no problems. We use this product to the extreme.

"Go with the Whisper."

I will always buy these here on Amazon for the price savings. It works okay for now but I hope it does not mess up my filter in the long run. Much better than the cartridges you get when you buy the filters. I have a Top Fin 10 power filter and these cartridges fit perfectly. Ignore all the noise about them being outdated they are a must-have buy it. I even used some in my Fluval 206 canister filter on my freshwater tank. But by two weeks, the output did drop.

"Nice sponge filter."

Particles fall off into the aquarium when you take them off to clean them. Small amounts of these bubbles can also help oxygenate the water over time. It includes 12 mesh filter bags& 12 packets of charcoal. Every tank should have intake sponges. If you don't know much about this just google it. The best part about these in my opinion, is the price. Fill with the supplied carbon and voila.

Especially if you have a take with shrimp or baby fish. We rinse the filters 2x a day and they remain in continuous 24 hour operation. I had to take a blade and run it through all the slats because the factory doesnt q. Just be super careful with the tubes! You will also need to replace their rechargeable batteries about every 2 years or so. I was having a problem with tiny fish getting sucked into the inlets. Don't get anything smaller than 750VA as you don't want to overload them.

I'm using this pad to HOB filters AC70 bottom and top of it’s sponge. Works well for my low flow Aquaclear 20. Outside tank on deck with just a few fish.

"Overall a good product!"

You may notice this brand is lower cost than some others. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. I have always had an undergravel filter and my aquariums. 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. It comes with the filter bag, bag frame, and charcoal media all separate.

Carbon pad measures 10.5" x 72" and 3/8" - 1/2" thick.
  • ELIMINATES ODOR AND DISCOLORATION! - Activated carbon, also known as activated charcoal, removes foul odors from aquarium and pond water LEAVING A CRISP CLEAN SMELL.

I bought these to put over the inlet to the filters in my aquariums. Plenty strong to support the rocks and gravel in my tank without sagging. Of course you will need to let the silicone cure before installing in water. The concentration of flow will mean faster clogging, lower flow and motor strain. You can cap off the ones you don't want to use. I have found you really have to scrub the outside to get everything cleaned out. Customizable in terms of media used.
