Marina 13315 First Impressions

"Bigger than expected."

It's a pain in the butt to put together the directions don’t do it that well. But a small simple rubber band fixed the issue quickly. I will keep using these and recommend them to anyone. Just be careful punching out the plastic. I will update more pictures later, once the water isnt cloudy. But if you don't weekly vacuum it up, it will eventually clog the filter. Particles fall off into the aquarium when you take them off to clean them.

Marina 13315 Final Thoughts

"Easy install."

Luckily I'm using powerheads and the weight of it helps hold it in place. I have been using an Aquaclear 50 on a 20g long planted tank. The first piece does get a bit dirty and usually only lasts a week. But by two weeks, the output did drop. These have prevented my original problem. I've definitely noticed a difference in my water quality. It's also a pretty substantial roll.

2. Fluval Output Nozzle for FX5 High Performance Canister Filter

Fluval A20226 First Impressions

"High quality."

I don't advise using a UG filter as the only filtration source in large tanks. I have used UG filters for many years. This filter system doesn't come with everything to you need. I purchased this bulk filter media for a Fluval 207 canister filter. I had to take a blade and run it through all the slats because the factory doesnt q. But if you don't weekly vacuum it up, it will eventually clog the filter. But a small simple rubber band fixed the issue quickly.

Fluval A20226 Final Thoughts

"Really good stuff."

We rinse the filters 2x a day and they remain in continuous 24 hour operation. I bought these because I was afraid my shrimp were getting sucked up in the filter. The best part about these in my opinion, is the price. But if you don't weekly vacuum it up, it will eventually clog the filter. Don't shut it off for more than a few minutes at a time. Don't restrict air-flow around them as they do get quite warm. I'm using this pad to HOB filters AC70 bottom and top of it’s sponge.

"Quiet and reliable."

For my smaller fish tank I find that it is just enough. But if you don't weekly vacuum it up, it will eventually clog the filter. I don't advise using a UG filter as the only filtration source in large tanks. Keep your stocking of creatures low. I end up cutting a small 2x3 inch square for each of my media baskets. TopFin frame is on the left, Tetra on the right. I use two layers of floss before the water goes to and through my chemical media.

Penn-Plax CCF3BMK Final Thoughts

"Overall fairly easy."

It was a struggle to keep the water clear before i got the goldfish. Right now I am letting the filter work it's magic. The injection molding for the plastics leave a lot to be desired. Of course you will need to let the silicone cure before installing in water. I rinsed and reuse same pad again 3 times and trashed later. Most plants won't like the highly oxygenated gravel and will die. I missed it in my opinion these filters are a must have.

4. AQUANEAT Bio Sponge Filter Media Pad Cut-to-fit Foam Up to 23" for Aquarium Fish Tank

User Ratings: 74

AQUANEAT First Impressions

"Very easy to do."

Work perfect on my shrimp tank to keep them out of the filter. Tank is clean and all my new shrimp are still alive! And provide a few low current areas in the tank for fish who are stressed to rest. Just be super careful with the tubes! Still, the price is of course fine at 4 for 6. Outside tank on deck with just a few fish. For my smaller fish tank I find that it is just enough.

  • AQUANEAT Bio Sponge Filter Media Pad Cut-to-fit Foam Up to 23" for Aquarium Fish Tank
  • Offers more surface area for both mechanical and biological filtration.
  • 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.
  • Traps large bits of waste and provides better water flow rate 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.

We rinse the filters 2x a day and they remain in continuous 24 hour operation. Nitrates in small doses are not as harmful to the fish as Ammonia. It includes 12 mesh filter bags& 12 packets of charcoal. Customizable in terms of media used.

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.

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.

Don't get anything smaller than 750VA as you don't want to overload them. We use this product to the extreme. It comes with carbon filters, and air stones. Right now I am letting the filter work it's magic. 7in, which is only about half the length of the unit. I purchased this bulk filter media for a Fluval 207 canister filter.

"5 gallon enchant tank."

Replace prefilter on pump inlet while filter is running. Fill with the supplied carbon and voila. We use this product to the extreme. It was nicely packaged and is a high quality filter material. I was having a problem with tiny fish getting sucked into the inlets. I had to take a blade and run it through all the slats because the factory doesnt q. I keep tubes of clear silicone sealer around.

"Pretty good."

The other tank is an old AIO retro tank I have with a media rack in it. The filters fit fine and I was happy to see that some carbon packs were included. So stock your tanks a few fish at a time. It's a pain in the butt to put together the directions don’t do it that well. I have always had an undergravel filter and my aquariums. Particles fall off into the aquarium when you take them off to clean them. My pad collected yellow cloudy color also all waste.

"Otherwise, very pleased."

Work perfect on my shrimp tank to keep them out of the filter. Every tank should have intake sponges. The main part is cleaning, that I need to find out. The measurements are about 9 cm long x 4 cm wide and the hole is about 2 cm. It comes with carbon filters, and air stones. It's a pain in the butt to put together the directions don’t do it that well. The air stones, plastic tubing, and charcoal were provided which one would expect.

"Good quantity for value."

Especially if you have a take with shrimp or baby fish. Most plants won't like the highly oxygenated gravel and will die. These have prevented my original problem. My tank is 12x36 so I utilized 3 of the panels. They do feel a little thin but we'll see how they hold up over time. Why not save some money to put towards more fish or supplies. I missed it in my opinion these filters are a must have.

I have been buying these bags for years. Don't believe people who tell you they are dangerous for your tank. Plenty strong to support the rocks and gravel in my tank without sagging. Better than branded media filters cartridges. It was a struggle to keep the water clear before i got the goldfish. Customizable in terms of media used. For my smaller fish tank I find that it is just enough.

"I have a 3."

I use two layers of floss before the water goes to and through my chemical media. We rinse the filters 2x a day and they remain in continuous 24 hour operation. But a small simple rubber band fixed the issue quickly. I have a Top Fin 10 power filter and these cartridges fit perfectly. 7in, which is only about half the length of the unit. I double the size and fold them and put the bagged carbon between the layers. Fun to modify your filter and clean tank as well.

"Great product."

Much better than the cartridges you get when you buy the filters. I will update more pictures later, once the water isnt cloudy. Fun to modify your filter and clean tank as well. The UG is certainly no exception to that. Nitrates in small doses are not as harmful to the fish as Ammonia. I keep tubes of clear silicone sealer around. I changed water 4 days in a row and still cloudy.
