"Love this sponge filter."

I end up cutting a small 2x3 inch square for each of my media baskets. I had to take a blade and run it through all the slats because the factory doesnt q. Customizable in terms of media used. Also work great as filler for canisters and other filters. I had to rinse the sponges after about 2. Also work great as filler for canisters and other filters. Fun to modify your filter and clean tank as well.

Danner 250151 Final Thoughts

"Great product and def."

It was nicely packaged and is a high quality filter material. So stock your tanks a few fish at a time. Within a matter of hours I now have a crystal clear tank with pristine water. For obvious reasons, don't put them directly above or below a tank. I have always had an undergravel filter and my aquariums. The concentration of flow will mean faster clogging, lower flow and motor strain. TopFin frame is on the left, Tetra on the right.

"Go with the Whisper."

The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. This is a lot of filter pad for your money. The material is a soft and not abrasive at all. This is a lot of filter pad for your money. I changed water 4 days in a row and still cloudy. If you have a nano tank with filter these would be perfect for that setup. My tank is 12x36 so I utilized 3 of the panels.

"No issues."

Even its quite costly, but it last long. Also work great as filler for canisters and other filters. I have always had an undergravel filter and my aquariums. Any floating debri will get caught in a sponge intake on the reverse power head kit. Right now I am letting the filter work it's magic. I bought these because I was afraid my shrimp were getting sucked up in the filter. I've saved so much money since switching, plus my tank stays cleaner.

"48 the decision is easy."

The first piece does get a bit dirty and usually only lasts a week. We operate a saltwater bait store, dealing in live shrimp and bull minnows. Why not save some money to put towards more fish or supplies. Plenty strong to support the rocks and gravel in my tank without sagging. I had to take a blade and run it through all the slats because the factory doesnt q. In 20 gallon and under sized tanks these start becoming feasible primary filters. For obvious reasons, don't put them directly above or below a tank.

BrightWater Final Thoughts

"Unbeatable at this price."

This is great for transporting aquarium life from location to location too. I can now afford to change all my filters at a fraction of the cost. Luckily I'm using powerheads and the weight of it helps hold it in place. The concentration of flow will mean faster clogging, lower flow and motor strain. You will also need to replace their rechargeable batteries about every 2 years or so. Small amounts of these bubbles can also help oxygenate the water over time. It made no sense why one was ten and the other was twenty.

"Overall fairly easy."

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.

"48 the decision is easy."

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. I took off two points because the pictures are misleading. Does the job and price was less or at least same as big retailers. We use this product to the extreme. The other tank is an old AIO retro tank I have with a media rack in it.

"Works well."

Work perfect on my shrimp tank to keep them out of the filter. The filters fit fine and I was happy to see that some carbon packs were included. But a small simple rubber band fixed the issue quickly. I use two layers of floss before the water goes to and through my chemical media. I have been using an Aquaclear 50 on a 20g long planted tank. Right now I am letting the filter work it's magic. You can cap off the ones you don't want to use.

Penn-Plax CFU29 Final Thoughts

"5 gallon enchant tank."

It comes with the filter bag, bag frame, and charcoal media all separate. This filter system doesn't come with everything to you need. I have found you really have to scrub the outside to get everything cleaned out. I had to rinse the sponges after about 2. But a small simple rubber band fixed the issue quickly. My pad collected yellow cloudy color also all waste. Fun to modify your filter and clean tank as well.

AQUANEAT First Impressions

"Very easy to do."

Work perfect on my shrimp tank to keep them out of the filter. Tank is clean and all my new shrimp are still alive! And provide a few low current areas in the tank for fish who are stressed to rest. Just be super careful with the tubes! Still, the price is of course fine at 4 for 6. Outside tank on deck with just a few fish. For my smaller fish tank I find that it is just enough.

  • AQUANEAT Bio Sponge Filter Media Pad Cut-to-fit Foam Up to 23" for Aquarium Fish Tank
  • Offers more surface area for both mechanical and biological filtration.
  • 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.
  • Traps large bits of waste and provides better water flow rate 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.

"See pictures."

Luckily I'm using powerheads and the weight of it helps hold it in place. I missed it in my opinion these filters are a must have. If your looking for a great media pad, stop here and order this! We rinse the filters 2x a day and they remain in continuous 24 hour operation. Nitrates in small doses are not as harmful to the fish as Ammonia. It includes 12 mesh filter bags& 12 packets of charcoal. Customizable in terms of media used.

Stop buying those expensive filters, buy this and make your own. It made no sense why one was ten and the other was twenty. 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. For my smaller fish tank I find that it is just enough. The concentration of flow will mean faster clogging, lower flow and motor strain. But by two weeks, the output did drop.

AQUA-TECH PL-T132-03 Final Thoughts

"Quiet and reliable."

Stop buying those expensive filters, buy this and make your own. If you have several aquariums, use separate UPS backups. It was easy to assemble and very effective! It's a pain in the butt to put together the directions don’t do it that well. I don't advise using a UG filter as the only filtration source in large tanks. I have used UG filters for many years. Don't believe people who tell you they are dangerous for your tank.

"I'm a client for life."

I use this in my filter for aquarium 55 gal. Once you do have everything it's a good running system. Keep your stocking of creatures low. I have a Top Fin 10 power filter and these cartridges fit perfectly. Also work great as filler for canisters and other filters. The filters fit fine and I was happy to see that some carbon packs were included. And provide a few low current areas in the tank for fish who are stressed to rest.

Fluval A20230 First Impressions

"I love it!"

It was exactly what I needed and fit beautifully. Particles fall off into the aquarium when you take them off to clean them. You can put power heads on the riser tubes to increase the flow through the filter. Especially if you have a take with shrimp or baby fish. Never use live rooting plants with UG filters. I have used UG filters for many years. The injection molding for the plastics leave a lot to be desired.

You may notice this brand is lower cost than some others. The filters fit fine and I was happy to see that some carbon packs were included. I just changed it today and the water is crystal clear-- no problems.
