Eheim 4005300 First Impressions

"Easy install."

Replace prefilter on pump inlet while filter is running. Works well for my low flow Aquaclear 20. I double the size and fold them and put the bagged carbon between the layers. Don't get anything smaller than 750VA as you don't want to overload them. The box comes with super easy and clear instructions. In 20 gallon and under sized tanks these start becoming feasible primary filters. I took off two points because the pictures are misleading.

Eheim 4005300 Final Thoughts

"I use the APC brand."

I have a Top Fin 10 power filter and these cartridges fit perfectly. Just be careful punching out the plastic. Tank is clean and all my new shrimp are still alive! I will always buy these here on Amazon for the price savings. Works well for my low flow Aquaclear 20. The main part is cleaning, that I need to find out. The injection molding for the plastics leave a lot to be desired.

"Excellent media!"

I bought these because I was afraid my shrimp were getting sucked up in the filter. I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter.

Golden Pearl Final Thoughts

"You get what you pay for."

The first 3 pics are of my RR tank with sump. Any floating debri will get caught in a sponge intake on the reverse power head kit. It was a struggle to keep the water clear before i got the goldfish. The other tank is an old AIO retro tank I have with a media rack in it. The foam is not coarse as illustrated; it's finer and denser. I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter. Fun to modify your filter and clean tank as well.

Penn-Plax CFU55 First Impressions

"Overall fairly easy."

This filter system doesn't come with everything to you need. I purchased these for an aquarium at school. That's a long time if you knew how nasty that many shrimp and minnows can be! You can run everything on battery backup sockets. But if you don't weekly vacuum it up, it will eventually clog the filter. If you're looking for new filters, go with these. I have been buying these bags for years.

  • Penn Plax Premium Under Gravel Filter System - for 40-55 Gallon Fish Tanks & Aquariums, Blue (CFU55)
  • Undergravel filter system includes 4 filter plates (each measuring 11.5" X 11.5") with extra large 1 inch adjustable lift tubes.
  • Filter is suitable for most 40 and 50 gallon aquariums. Clips to hold each section securely together are included.
  • 2 carbon filter cartridges remove odors, and water discoloration by trapping the pollutants in the pores of the carbon.
  • This undergravel filter hides from view for maximum aesthetics. Safe for use in both freshwater and saltwater tanks.
  • Effortless setup and easy maintenance make this premium undergravel filter a must have for all home aquariums.  Simply place filter plates at the bottom of the tank and cover with gravel.

Penn-Plax CFU55 Final Thoughts

"Pretty good."

I have a Top Fin 10 power filter and these cartridges fit perfectly. So here is the product size on the boxes that isn't included in the description! It's a pain in the butt to put together the directions don’t do it that well. It was exactly what I needed and fit beautifully. For obvious reasons, don't put them directly above or below a tank. You can cap off the ones you don't want to use. I have used UG filters for many years.

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.

Fluval A1376 Final Thoughts

"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.

AQUANEAT First Impressions

"That said."

Tank is clean and all my new shrimp are still alive! Keep your stocking of creatures low. It was easy to assemble and very effective! The more you overpopulate your tank, the more frequently you'll have to do this. It includes 12 mesh filter bags& 12 packets of charcoal. The more you overpopulate your tank, the more frequently you'll have to do this. Ignore all the noise about them being outdated they are a must-have buy it.

  • AQUANEAT Aquarium Open Cell Foam Sheet Bio Sponge Filter Media Pad HMF Fish Tank Sump Divider 11" x 10.25" x 2"/ 23" x 10.25" x 2"
  • Dimension: 23" Lx 10.25"W x 2"H; PPI: 40 Fine Pad
  • The open cell sponge has a much larger inner surface area for beneficial biological capacity, and produces both mechanical and biological filtration.
  • This filter pad can be cut to fit and used as a pre-filter for any aquarium or pond filter, sump, wet/dry, canister, power filter etc. or your HMF DIY project.
  • The reticulated structure also provides better flow rate of water and less chance of clog.
  • The size of pores is measure in pores per inch (PPI). The sponge with higher PPI has more pores in it. More pores means larger biological filtration capacity but with less water flow through rate and needs to be cleaned more often. It is recommended to use combination of sponge with difference PPI to get the best result.

"Easy install."

I bought these to put over the inlet to the filters in my aquariums. The filter material itself is good quality material too that doesn't break open. My pad collected yellow cloudy color also all waste. Why not save some money to put towards more fish or supplies. If you have several aquariums, use separate UPS backups. Especially if you have a take with shrimp or baby fish. It was a struggle to keep the water clear before i got the goldfish.

Tetra 26169 First Impressions

"I couldn't believe it!"

Small amounts of these bubbles can also help oxygenate the water over time. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. Any floating debri will get caught in a sponge intake on the reverse power head kit. Within a matter of hours I now have a crystal clear tank with pristine water. The UG is certainly no exception to that. The concentration of flow will mean faster clogging, lower flow and motor strain. I changed water 4 days in a row and still cloudy.

"& was still intact."

I will update more pictures later, once the water isnt cloudy. I have always had an undergravel filter and my aquariums. We use this product to the extreme. If you don't know much about this just google it. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge. Don't shut it off for more than a few minutes at a time. You may notice this brand is lower cost than some others.

"Very easy to do."

I even used some in my Fluval 206 canister filter on my freshwater tank. Why not save some money to put towards more fish or supplies. It eventually begins to decompose into ammonia which is harmful to your fish. Did all of mine The same, never ripped a one and they all fit like a glove. Never use live rooting plants with UG filters. Much better than the cartridges you get when you buy the filters. Lets start with the amount of filter material you get.

User Ratings: 44 28

XEOGUIYA First Impressions

"I've bought 3 of these."

Within a matter of hours I now have a crystal clear tank with pristine water. Of course you will need to let the silicone cure before installing in water. I had to take a blade and run it through all the slats because the factory doesnt q. I use this in my filter for aquarium 55 gal. I keep tubes of clear silicone sealer around. This is a lot of filter pad for your money. If you have several aquariums, use separate UPS backups.

  • XEOGUIYA Double Sponge Filter, Bio-Chemical Submersible Sponge Filter for Aquarium Fish Tank, Up to 60 Gallons
  • Aquarium filter: Made of high-quality plastic and filter sponges, the ultra-quiet design provides a good aquatic environment for fish.
  • High-efficiency filtration: The two sponges serve a dual purpose, which can quickly establish a biological filter, provide a larger surface area and speed up circulation, and maintain a clean effect during filtration.
  • Easy to install: Please soak the filter cotton with fish tank water before use, then connect the air hose to the small nozzle, and then turn on the air pump to provide the filtering function for the fish. Come with 2 suction cups, which can be installed anywhere on the glass of the fish tank.
  • Simple care: It is recommended to clean the filter cotton with fish tank water to avoid destroying the formed nitrifying colonies. Clean the sponge once a month, and replace the filter cotton at most every 5 to 6 months.
  • Note: Please do not use an oversized air pump to avoid uneven mixing of water and air. The packaging includes: 1x sponge filter, with a packaging box.

9. V AquaVista Aquatics Háifoss SandFall Filter

V AquaVista Aquatics SFF454824A First Impressions

"They do the job well!"

Fill with the supplied carbon and voila. I don't advise using a UG filter as the only filtration source in large tanks. This improves flow and prolongs time between cleaning. It was easy to assemble and very effective! The first 3 pics are of my RR tank with sump. I purchased this bulk filter media for a Fluval 207 canister filter. It comes with the filter bag, bag frame, and charcoal media all separate.

"They work great!"

I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter. 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. It comes with the filter bag, bag frame, and charcoal media all separate. We rinse the filters 2x a day and they remain in continuous 24 hour operation. Even its quite costly, but it last long. I use two layers of floss before the water goes to and through my chemical media.

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.
