"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.

"Hope this helps!"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. My tank is 12x36 so I utilized 3 of the panels. Every tank should have intake sponges. I end up cutting a small 2x3 inch square for each of my media baskets. I've saved so much money since switching, plus my tank stays cleaner. Right now I am letting the filter work it's magic.

"It is what i wanted."Works well for my low flow Aquaclear 20. I had to rinse the sponges after about 2. It's a pain in the butt to put together the directions don’t do it that well. It was nicely packaged and is a high quality filter material. Lets start with the amount of filter material you get. These have prevented my original problem. The foam is not coarse as illustrated; it's finer and denser.

"Pretty good."Fill with the supplied carbon and voila. You can put power heads on the riser tubes to increase the flow through the filter. Customizable in terms of media used. It was easy to assemble and very effective! I just changed it today and the water is crystal clear-- no problems. It works okay for now but I hope it does not mess up my filter in the long run. I was having a problem with tiny fish getting sucked into the inlets.

"5 minutes of work!"Cut slightly oversized, it seems very effective as a particulate filter. I will update more pictures later, once the water isnt cloudy. I have a Top Fin 10 power filter and these cartridges fit perfectly. Just be careful punching out the plastic. TopFin frame is on the left, Tetra on the right. I took off two points because the pictures are misleading. Have been using this product for few month for my planted tank.

"I couldn't believe it!"Fill with the supplied carbon and voila. It was nicely packaged and is a high quality filter material. Fish that are constantly swimming hard will tire and die from stress. You can also buy solutions that have the bacteria in them to also get started faster. I use two layers of floss before the water goes to and through my chemical media. If you have several aquariums, use separate UPS backups. I purchased these for an aquarium at school.

"Nada, zilch, nugga."The concentration of flow will mean faster clogging, lower flow and motor strain. Nitrates in small doses are not as harmful to the fish as Ammonia. Small amounts of these bubbles can also help oxygenate the water over time. Stop buying those expensive filters, buy this and make your own. I have been buying these bags for years. I have always had an undergravel filter and my aquariums. Nitrates in small doses are not as harmful to the fish as Ammonia.

"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.
