"Bigger than expected."

But by two weeks, the output did drop. I don't advise using a UG filter as the only filtration source in large tanks. So here is the product size on the boxes that isn't included in the description! Replace prefilter on pump inlet while filter is running. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge. But if you don't weekly vacuum it up, it will eventually clog the filter. And provide a few low current areas in the tank for fish who are stressed to rest.

Koral Filters Final Thoughts

"I'm a client for life."

Make sure to select the Medium size from Tetra. I had to take a blade and run it through all the slats because the factory doesnt q. Also work great as filler for canisters and other filters. Nitrates in small doses are not as harmful to the fish as Ammonia. Because they are the smart thing to do when you keep aquariums. I have always had an undergravel filter and my aquariums. You can run everything on battery backup sockets.

"Great product and def."

I purchased this bulk filter media for a Fluval 207 canister filter. Don't get anything smaller than 750VA as you don't want to overload them. Customizable in terms of media used. 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. Have been using this product for few month for my planted tank. They are easy to clean but are very small.

Koral Filters Final Thoughts

"I've bought 3 of these."

The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. 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. I was having a problem with tiny fish getting sucked into the inlets. Because they are the smart thing to do when you keep aquariums. Still, the price is of course fine at 4 for 6. I had a 90 gallon aquarium that I did not use an undergravel filter in.

"Good quality."

Did all of mine The same, never ripped a one and they all fit like a glove. This filter system doesn't come with everything to you need. Don't believe people who tell you they are dangerous for your tank. It works okay for now but I hope it does not mess up my filter in the long run. But by two weeks, the output did drop. I purchased these for an aquarium at school. You can also buy solutions that have the bacteria in them to also get started faster.

"Thank you, Marineland!"

If you have several aquariums, use separate UPS backups. Does the job and price was less or at least same as big retailers. But by two weeks, the output did drop. So stock your tanks a few fish at a time. You can run everything on battery backup sockets. And provide a few low current areas in the tank for fish who are stressed to rest. I even used some in my Fluval 206 canister filter on my freshwater tank.

"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.

"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.

AQUANEAT Final Thoughts

"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.

Acurel LLC 2500 First Impressions

"I would buy it again."

The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. Once you do have everything it's a good running system. This improves flow and prolongs time between cleaning. Luckily I'm using powerheads and the weight of it helps hold it in place. I purchased these for an aquarium at school. Even its quite costly, but it last long. I've saved so much money since switching, plus my tank stays cleaner.

Acurel LLC 2500 Final Thoughts

"Happy Happy Joy Joy!"

We use this product to the extreme. Fill with the supplied carbon and voila. I use two layers of floss before the water goes to and through my chemical media. Cut slightly oversized, it seems very effective as a particulate filter. Right now I am letting the filter work it's magic. Of course you will need to let the silicone cure before installing in water. I will update more pictures later, once the water isnt cloudy.

"Maybe I'll call them."

Cut slightly oversized, it seems very effective as a particulate filter. Better than branded media filters cartridges. Don't restrict air-flow around them as they do get quite warm. I keep tubes of clear silicone sealer around. I will be using Koral Filter material from now on. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder.

The first piece does get a bit dirty and usually only lasts a week. It works okay for now but I hope it does not mess up my filter in the long run. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. It was a struggle to keep the water clear before i got the goldfish. Does the job and price was less or at least same as big retailers. I replace my filter material in my IM Nuvo 20 reef tank every week. Most plants won't like the highly oxygenated gravel and will die.

"I have 2 tanks."

You may notice this brand is lower cost than some others. Never use live rooting plants with UG filters. I bought these because I was afraid my shrimp were getting sucked up in the filter. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. I purchase the 8 pack size Large and fits great on my TopFin 40 Gallon Filter. The filters fit fine and I was happy to see that some carbon packs were included. It was easy to assemble and very effective!

"Overall fairly easy."

So here is the product size on the boxes that isn't included in the description! The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. You can put power heads on the riser tubes to increase the flow through the filter. Don't get anything smaller than 750VA as you don't want to overload them. Fun to modify your filter and clean tank as well. I can now afford to change all my filters at a fraction of the cost. They are easy to clean but are very small.

I don't advise using a UG filter as the only filtration source in large tanks. I keep tubes of clear silicone sealer around. Much better than the cartridges you get when you buy the filters. I just changed it today and the water is crystal clear-- no problems. I don't advise using a UG filter as the only filtration source in large tanks. They are easy to clean but are very small.

"But they last a while."

We use this product to the extreme. I had a 90 gallon aquarium that I did not use an undergravel filter in. I will always buy these here on Amazon for the price savings. Make sure to select the Medium size from Tetra. I purchased these for an aquarium at school. I end up cutting a small 2x3 inch square for each of my media baskets. If you have a nano tank with filter these would be perfect for that setup.

Don't believe people who tell you they are dangerous for your tank. The concentration of flow will mean faster clogging, lower flow and motor strain. TopFin frame is on the left, Tetra on the right. Fun to modify your filter and clean tank as well. Even its quite costly, but it last long. The material is a soft and not abrasive at all. The first 3 pics are of my RR tank with sump.
