"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.

"The hole is smaller."

Tank is clean and all my new shrimp are still alive! It's also a pretty substantial roll. If you have several aquariums, use separate UPS backups. My pad collected yellow cloudy color also all waste. Once you do have everything it's a good running system. In 20 gallon and under sized tanks these start becoming feasible primary filters. For my smaller fish tank I find that it is just enough.

"And it WAS a problem."

Cut slightly oversized, it seems very effective as a particulate filter. Never use live rooting plants with UG filters. They are easy to clean but are very small. It eventually begins to decompose into ammonia which is harmful to your fish. The concentration of flow will mean faster clogging, lower flow and motor strain. This filter system doesn't come with everything to you need. Even its quite costly, but it last long.

"I would recommend these."

Keep your stocking of creatures low. If you have several aquariums, use separate UPS backups. The injection molding for the plastics leave a lot to be desired. My pad collected yellow cloudy color also all waste. I double the size and fold them and put the bagged carbon between the layers. I've definitely noticed a difference in my water quality. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge.

"Without making a mess!"

The best part about these in my opinion, is the price. Plenty strong to support the rocks and gravel in my tank without sagging. I rinsed and reuse same pad again 3 times and trashed later. The more you overpopulate your tank, the more frequently you'll have to do this. I have been buying these bags for years. These have prevented my original problem. I missed it in my opinion these filters are a must have.

"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.

"5 minutes of work!"

We use this product to the extreme. Fill with the supplied carbon and voila. The other tank is an old AIO retro tank I have with a media rack in it. I have always had an undergravel filter and my aquariums. I had to rinse the sponges after about 2. Any floating debri will get caught in a sponge intake on the reverse power head kit. And provide a few low current areas in the tank for fish who are stressed to rest.

"Hope this helps!"

This is a lot of filter pad for your money. I keep tubes of clear silicone sealer around. But a small simple rubber band fixed the issue quickly. Fish that are constantly swimming hard will tire and die from stress. It eventually begins to decompose into ammonia which is harmful to your fish. Don't shut it off for more than a few minutes at a time. Lets start with the amount of filter material you get.

"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. I was having a problem with tiny fish getting sucked into the inlets.

"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.

Any floating debri will get caught in a sponge intake on the reverse power head kit. It was exactly what I needed and fit beautifully. They do feel a little thin but we'll see how they hold up over time. Customizable in terms of media used. That's a long time if you knew how nasty that many shrimp and minnows can be!

"I've bought 3 of these."

Don't shut it off for more than a few minutes at a time. I purchased these for an aquarium at school. My pad collected yellow cloudy color also all waste. Just be super careful with the tubes! I can now afford to change all my filters at a fraction of the cost. Better than branded media filters cartridges. For obvious reasons, don't put them directly above or below a tank.

"5 gallon tank."

Fun to modify your filter and clean tank as well. Don't restrict air-flow around them as they do get quite warm. 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. Don't get anything smaller than 750VA as you don't want to overload them. Right now I am letting the filter work it's magic.

"Hand down the best."

If you have several aquariums, use separate UPS backups. Of course you will need to let the silicone cure before installing in water. Don't get anything smaller than 750VA as you don't want to overload them. The other tank is an old AIO retro tank I have with a media rack in it. The air stones, plastic tubing, and charcoal were provided which one would expect. It comes with carbon filters, and air stones. In 20 gallon and under sized tanks these start becoming feasible primary filters.

So here is the product size on the boxes that isn't included in the description! Plenty strong to support the rocks and gravel in my tank without sagging. We use this product to the extreme. Have been using this product for few month for my planted tank. The best part about these in my opinion, is the price. The first piece does get a bit dirty and usually only lasts a week.
