"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.

"Maybe I'll call them."

Fun to modify your filter and clean tank as well. Luckily I'm using powerheads and the weight of it helps hold it in place. The first piece does get a bit dirty and usually only lasts a week. Make sure to select the Medium size from Tetra. We rinse the filters 2x a day and they remain in continuous 24 hour operation. I have been using an Aquaclear 50 on a 20g long planted tank. The air stones, plastic tubing, and charcoal were provided which one would expect.

"See pictures."

But by two weeks, the output did drop. This improves flow and prolongs time between cleaning. If your looking for a great media pad, stop here and order this! It was easy to assemble and very effective! So stock your tanks a few fish at a time. You will also need to replace their rechargeable batteries about every 2 years or so. The filters fit fine and I was happy to see that some carbon packs were included.

"Excellent media!"

This is great for transporting aquarium life from location to location too. If you have a nano tank with filter these would be perfect for that setup. It made no sense why one was ten and the other was twenty. Did all of mine The same, never ripped a one and they all fit like a glove. Because they are the smart thing to do when you keep aquariums. I purchased this bulk filter media for a Fluval 207 canister filter. I purchased these for an aquarium at school.

Also work great as filler for canisters and other filters. You may notice this brand is lower cost than some others. The first piece does get a bit dirty and usually only lasts a week. Customizable in terms of media used. You get what you pay for but i had to work on it a lot. Once you do have everything it's a good running system.

"It's amazing."

Small amounts of these bubbles can also help oxygenate the water over time. We rinse the filters 2x a day and they remain in continuous 24 hour operation. It was exactly what I needed and fit beautifully. Don't shut it off for more than a few minutes at a time. This is great for transporting aquarium life from location to location too. Even its quite costly, but it last long. Cut slightly oversized, it seems very effective as a particulate filter.

"The hole is smaller."

The material is a soft and not abrasive at all. Any floating debri will get caught in a sponge intake on the reverse power head kit. Just be super careful with the tubes! Lets start with the amount of filter material you get. I have a Top Fin 10 power filter and these cartridges fit perfectly. I had to take a blade and run it through all the slats because the factory doesnt q. Never use live rooting plants with UG filters.

I'm using this pad to HOB filters AC70 bottom and top of it’s sponge. It was nicely packaged and is a high quality filter material. Don't restrict air-flow around them as they do get quite warm. Lets start with the amount of filter material you get. Why not save some money to put towards more fish or supplies. It was exactly what I needed and fit beautifully. The other tank is an old AIO retro tank I have with a media rack in it.

"Fit great into my filter."

It eventually begins to decompose into ammonia which is harmful to your fish. If you have a nano tank with filter these would be perfect for that setup. I have been buying these bags for years. In 20 gallon and under sized tanks these start becoming feasible primary filters. I use two layers of floss before the water goes to and through my chemical media. I bought these because I was afraid my shrimp were getting sucked up in the filter. Particles fall off into the aquarium when you take them off to clean them.

"They do the job well!"

Work perfect on my shrimp tank to keep them out of the filter. I have used UG filters for many years. The filters fit fine and I was happy to see that some carbon packs were included. Still, the price is of course fine at 4 for 6. Fun to modify your filter and clean tank as well. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge. The UG is certainly no exception to that.

"Huge mess."

Even its quite costly, but it last long. So stock your tanks a few fish at a time. Don't get anything smaller than 750VA as you don't want to overload them. 7in, which is only about half the length of the unit. Work perfect on my shrimp tank to keep them out of the filter. For my smaller fish tank I find that it is just enough. I will always buy these here on Amazon for the price savings.

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.

"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.

"This is a great product."

I will update more pictures later, once the water isnt cloudy. I replace my filter material in my IM Nuvo 20 reef tank every week. Stop buying those expensive filters, buy this and make your own. The UG is certainly no exception to that. This improves flow and prolongs time between cleaning. These work great as pre filter sponge on my quiet flow 10.

"And it WAS a problem."

Just be careful punching out the plastic. I also suppose my measuring tape may be off, but I would not think so. Lets start with the amount of filter material you get. Especially if you have a take with shrimp or baby fish. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. I use this in my filter for aquarium 55 gal. But a small simple rubber band fixed the issue quickly.
