"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.

"Just cut it to size."

We operate a saltwater bait store, dealing in live shrimp and bull minnows. Because they are the smart thing to do when you keep aquariums. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge. For my smaller fish tank I find that it is just enough. Most plants won't like the highly oxygenated gravel and will die. I end up cutting a small 2x3 inch square for each of my media baskets. I just changed it today and the water is crystal clear-- no problems.

"Good quality."

The air stones, plastic tubing, and charcoal were provided which one would expect. Have been using this product for few month for my planted tank. Just be careful punching out the plastic. It was a struggle to keep the water clear before i got the goldfish. Customizable in terms of media used. Works well for my low flow Aquaclear 20. The material is a soft and not abrasive at all.

"STICK WITH THE ORIGINAL."

I missed it in my opinion these filters are a must have. Keep your stocking of creatures low. They are easy to clean but are very small. Right now I am letting the filter work it's magic. This improves flow and prolongs time between cleaning. For my smaller fish tank I find that it is just enough. I double the size and fold them and put the bagged carbon between the layers.

"5 gallon tank."

Within a matter of hours I now have a crystal clear tank with pristine water. I had to rinse the sponges after about 2. Right now I am letting the filter work it's magic. If you have several aquariums, use separate UPS backups. Lets start with the amount of filter material you get. I took off two points because the pictures are misleading. It eventually begins to decompose into ammonia which is harmful to your fish.

User Ratings: 82 1

Aquatic Experts First Impressions

"Good price."

Of course you will need to let the silicone cure before installing in water. I've definitely noticed a difference in my water quality. The more you overpopulate your tank, the more frequently you'll have to do this. I will be using Koral Filter material from now on. If you don't know much about this just google it. Tank is clean and all my new shrimp are still alive! I keep tubes of clear silicone sealer around.

"Nada, zilch, nugga."

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 would recommend these."

This filter system doesn't come with everything to you need. This is great for transporting aquarium life from location to location too. I even used some in my Fluval 206 canister filter on my freshwater tank. Don't believe people who tell you they are dangerous for your tank. Why not save some money to put towards more fish or supplies. This is a lot of filter pad for your money. You can put power heads on the riser tubes to increase the flow through the filter.

"Love this stuff."

The other tank is an old AIO retro tank I have with a media rack in it. The concentration of flow will mean faster clogging, lower flow and motor strain. You may notice this brand is lower cost than some others. Every tank should have intake sponges. Of course you will need to let the silicone cure before installing in water. The other tank is an old AIO retro tank I have with a media rack in it. These have prevented my original problem.

"ALL I can say is wow."

Ignore all the noise about them being outdated they are a must-have buy it. The material is a soft and not abrasive at all. But by two weeks, the output did drop.

"It cuts easily."

Once you do have everything it's a good running system. We rinse the filters 2x a day and they remain in continuous 24 hour operation. Right now I am letting the filter work it's magic. Better than branded media filters cartridges. I changed water 4 days in a row and still cloudy. TopFin frame is on the left, Tetra on the right. I rinsed and reuse same pad again 3 times and trashed later.

"It's absolutely perfect."

I have a Top Fin 10 power filter and these cartridges fit perfectly. I double the size and fold them and put the bagged carbon between the layers. Luckily I'm using powerheads and the weight of it helps hold it in place. Make sure to select the Medium size from Tetra. Replace prefilter on pump inlet while filter is running. I had to take a blade and run it through all the slats because the factory doesnt q. It was a struggle to keep the water clear before i got the goldfish.

"Great product and def."

It includes 12 mesh filter bags& 12 packets of charcoal. I purchased these for an aquarium at school. But if you don't weekly vacuum it up, it will eventually clog the filter. Much better than the cartridges you get when you buy the filters. The Tetra Medium bio-bag slip easily on an original Top Fin plastic holder. If you have a nano tank with filter these would be perfect for that setup. It comes with carbon filters, and air stones.

7in, which is only about half the length of the unit. I even used some in my Fluval 206 canister filter on my freshwater tank. Plenty strong to support the rocks and gravel in my tank without sagging. Outside tank on deck with just a few fish. It made no sense why one was ten and the other was twenty. I end up cutting a small 2x3 inch square for each of my media baskets. Why not save some money to put towards more fish or supplies.

"You get what you pay for."

I end up cutting a small 2x3 inch square for each of my media baskets. These work great as pre filter sponge on my quiet flow 10. Lets start with the amount of filter material you get. I have always had an undergravel filter and my aquariums. It's a pain in the butt to put together the directions don’t do it that well. For obvious reasons, don't put them directly above or below a tank. For my smaller fish tank I find that it is just enough.

Especially if you have a take with shrimp or baby fish. We rinse the filters 2x a day and they remain in continuous 24 hour operation.

You will also need to replace their rechargeable batteries about every 2 years or so. I was having a problem with tiny fish getting sucked into the inlets.
