"Bigger than expected."

It comes with the filter bag, bag frame, and charcoal media all separate. The filters fit fine and I was happy to see that some carbon packs were included. Lets start with the amount of filter material you get. If you don't know much about this just google it. I missed it in my opinion these filters are a must have. This is great for transporting aquarium life from location to location too. Within a matter of hours I now have a crystal clear tank with pristine water.

"Nice sponge filter."

Lets start with the amount of filter material you get. Don't get anything smaller than 750VA as you don't want to overload them. For obvious reasons, don't put them directly above or below a tank. I've definitely noticed a difference in my water quality. Fish that are constantly swimming hard will tire and die from stress. Right now I am letting the filter work it's magic. I have always had an undergravel filter and my aquariums.

"So far so good!"

The box comes with super easy and clear instructions. Keep your stocking of creatures low. I have been buying these bags for years. I replace my filter material in my IM Nuvo 20 reef tank every week. It was nicely packaged and is a high quality filter material. The best part about these in my opinion, is the price. I have been buying these bags for years.

"Looks great!"

I have been using an Aquaclear 50 on a 20g long planted tank. I have been buying these bags for years. Stop buying those expensive filters, buy this and make your own. I purchased this bulk filter media for a Fluval 207 canister filter. You can run everything on battery backup sockets. It was exactly what I needed and fit beautifully. Just be super careful with the tubes!

Penn-Plax CCF229 First Impressions

"Good luck y'all!"

You will also need to replace their rechargeable batteries about every 2 years or so. It was easy to assemble and very effective! You can put power heads on the riser tubes to increase the flow through the filter. We use this product to the extreme. The injection molding for the plastics leave a lot to be desired. I've saved so much money since switching, plus my tank stays cleaner. A great addition to the filtration system.

  • Penn Plax Cascade 700/1000 GPH Canister Filter Aquarium Bio Sponge Replacement, 1 Pack

"I use the APC brand."

Customizable in terms of media used. But by two weeks, the output did drop. This is a lot of filter pad for your money. Don't restrict air-flow around them as they do get quite warm. We operate a saltwater bait store, dealing in live shrimp and bull minnows. Plenty strong to support the rocks and gravel in my tank without sagging. This filter system doesn't come with everything to you need.

"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.

Seachem 6581 First Impressions

"I use the APC brand."

But by two weeks, the output did drop. 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. Does the job and price was less or at least same as big retailers. Fill with the supplied carbon and voila. Fill with the supplied carbon and voila. You can also buy solutions that have the bacteria in them to also get started faster.

  • Seachem Tidal Power Aquarium Filter - 35 Gallon Large Fish Tank Filter
  • FLOW REGULATION: The fully adjustable flow regulation feature on the Tidal Power Filter adjusts performance to a specific aquarium volume, type, or provide an environment for fish that prefer more or less water movement or oxygenation. Adjust the dial from anywhere between 450 gallons per hour down to a gentle 90 gallons per hour.
  • SURFACE SKIMMER: The surface skimmer on the Tidal Power Filter will capture the water from just below the surface, where excreted fish oils accumulate, as well as deeper in the tank to remove floating debris.
  • ADJUSTABLE INTAKE FLOW: With Tidal’s dual intake, it pulls water in through the telescoping pipe below the surface and at the surface through the surface skimmer. Easily adjust how much flow comes from the underwater intake pipe versus the surface skimmer with the intake flow dial.
  • HEATER HOLDER: A heater can be attached to the side of the Tidal Power Filter with an optional heater clip, allowing for better dispersal of heated water throughout your tank or aquarium.
  • MAINTENANCE ALERT: When filtration media becomes clogged with detritus and affects the flow of water, the Tidal Power Filter redirects water around the filter and back into the aquarium through an outlet on the side. The redirected water then pushed up the blue maintenance alert on the top of the filter, signaling that the filter needs to be cleaned.
  • Ventilation slots in the lid of the filter and aeration grooves in the outflow ensure that water returned to the tank is fully oxygenated and maximize gas exchange during filtration.
  • The pump pushes water up into the basket of the filter, entering through the bottom of the basket and being pushed out the top. A bottom-to-top flow ensures that water comes into contact will all filter media, and cannot go around or over filter media as with hang on back filters with a back-to-front flow.
  • Over time, filtration media can become clogged with detritus reducing or obstructing the flow of water through it. When this happens in Tidal filters, water is redirected around the filter and back into the aquarium through an outlet on the side. The redirected water pushes up the blue maintenance alert on the top of the filter, signaling that the filter needs to be cleaned.

"Flow rate adjustment."

Work perfect on my shrimp tank to keep them out of the filter. Fun to modify your filter and clean tank as well. Even its quite costly, but it last long. If you're looking for new filters, go with these. It was nicely packaged and is a high quality filter material. Every tank should have intake sponges. I had to take a blade and run it through all the slats because the factory doesnt q.

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.

"I couldn't believe it!"

It was nicely packaged and is a high quality filter material. I took off two points because the pictures are misleading. Stop buying those expensive filters, buy this and make your own. I use this in my filter for aquarium 55 gal. You will also need to replace their rechargeable batteries about every 2 years or so. It includes 12 mesh filter bags& 12 packets of charcoal. But if you don't weekly vacuum it up, it will eventually clog the filter.

"It cuts easily."

Right now I am letting the filter work it's magic. If you're looking for new filters, go with these. It eventually begins to decompose into ammonia which is harmful to your fish. It made no sense why one was ten and the other was twenty. 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. For obvious reasons, don't put them directly above or below a tank.

"Glad I bought 2."

You will also need to replace their rechargeable batteries about every 2 years or so. The foam is not coarse as illustrated; it's finer and denser. This is great for transporting aquarium life from location to location too. It works okay for now but I hope it does not mess up my filter in the long run. If you have several aquariums, use separate UPS backups. I will be using Koral Filter material from now on. I will update more pictures later, once the water isnt cloudy.

If you have a nano tank with filter these would be perfect for that setup. They do feel a little thin but we'll see how they hold up over time.

Keep your stocking of creatures low. I rinsed and reuse same pad again 3 times and trashed later. Replace prefilter on pump inlet while filter is running. For obvious reasons, don't put them directly above or below a tank. Because they are the smart thing to do when you keep aquariums. Make sure to select the Medium size from Tetra. The best part about these in my opinion, is the price.
