"They do the job well!"

It made no sense why one was ten and the other was twenty. It was a struggle to keep the water clear before i got the goldfish. It eventually begins to decompose into ammonia which is harmful to your fish. Right now I am letting the filter work it's magic. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. Also work great as filler for canisters and other filters.

SunSun HW-304B Final Thoughts

"I would buy it again."

I have a Top Fin 10 power filter and these cartridges fit perfectly. It was nicely packaged and is a high quality filter material. Also work great as filler for canisters and other filters. Just be super careful with the tubes! Don't shut it off for more than a few minutes at a time. I use two layers of floss before the water goes to and through my chemical media. The injection molding for the plastics leave a lot to be desired.

"5 gallon tank."

I change my filters once a month, so the 12 pack lasts me a year! They do feel a little thin but we'll see how they hold up over time. My tank is 12x36 so I utilized 3 of the panels. Why not save some money to put towards more fish or supplies. These work great as pre filter sponge on my quiet flow 10. I have been using an Aquaclear 50 on a 20g long planted tank. Tank is clean and all my new shrimp are still alive!

"Huge mess."

This filter system doesn't come with everything to you need. The box comes with super easy and clear instructions. These have prevented my original problem. Especially if you have a take with shrimp or baby fish. If your looking for a great media pad, stop here and order this! I also suppose my measuring tape may be off, but I would not think so. Keep your stocking of creatures low.

"5 gallon enchant tank."

I was having a problem with tiny fish getting sucked into the inlets. I also suppose my measuring tape may be off, but I would not think so. Also work great as filler for canisters and other filters. I changed water 4 days in a row and still cloudy. Fill with the supplied carbon and voila. Especially if you have a take with shrimp or baby fish. Most plants won't like the highly oxygenated gravel and will die.

"It's amazing."

Make sure to select the Medium size from Tetra. I even used some in my Fluval 206 canister filter on my freshwater tank. I missed it in my opinion these filters are a must have. Keep your stocking of creatures low. Better than branded media filters cartridges. We rinse the filters 2x a day and they remain in continuous 24 hour operation. I use two layers of floss before the water goes to and through my chemical media.

"I bought the 6ft roll."

The filter material itself is good quality material too that doesn't break open. I have been buying these bags for years. Customizable in terms of media used. Don't get anything smaller than 750VA as you don't want to overload them. Most plants won't like the highly oxygenated gravel and will die.

"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.

"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.

"I cycle lots of tanks."

Because they are the smart thing to do when you keep aquariums. Luckily I'm using powerheads and the weight of it helps hold it in place. You can put power heads on the riser tubes to increase the flow through the filter. I was having a problem with tiny fish getting sucked into the inlets. Work perfect on my shrimp tank to keep them out of the filter. I just changed it today and the water is crystal clear-- no problems. Small amounts of these bubbles can also help oxygenate the water over time.

"It's absolutely perfect."

The more you overpopulate your tank, the more frequently you'll have to do this. TopFin frame is on the left, Tetra on the right. I just changed it today and the water is crystal clear-- no problems.

Penn-Plax CCF4BMK First Impressions

"I would recommend these."

It was easy to assemble and very effective! Fish that are constantly swimming hard will tire and die from stress. Much better than the cartridges you get when you buy the filters. I rinsed and reuse same pad again 3 times and trashed later. Don't restrict air-flow around them as they do get quite warm. Keep your stocking of creatures low. So stock your tanks a few fish at a time.

"Otherwise, very pleased."

I have used UG filters for many years. Also work great as filler for canisters and other filters. I have always had an undergravel filter and my aquariums. Keep your stocking of creatures low. 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.

"Can't beat the price!"

If you have several aquariums, use separate UPS backups. I have been buying these bags for years. I was having a problem with tiny fish getting sucked into the inlets. Customizable in terms of media used. Of course you will need to let the silicone cure before installing in water. I double the size and fold them and put the bagged carbon between the layers. The main part is cleaning, that I need to find out.

"Excellent media!"

Better than branded media filters cartridges. It was easy to assemble and very effective! It works okay for now but I hope it does not mess up my filter in the long run. I took off two points because the pictures are misleading. Make sure to select the Medium size from Tetra. For obvious reasons, don't put them directly above or below a tank. The first piece does get a bit dirty and usually only lasts a week.
