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.

"Works great."

TopFin frame is on the left, Tetra on the right. I can now afford to change all my filters at a fraction of the cost. For my smaller fish tank I find that it is just enough. A great addition to the filtration system. Works well for my low flow Aquaclear 20. I have been using an Aquaclear 50 on a 20g long planted tank. It was a struggle to keep the water clear before i got the goldfish.

"Hehehehehe shhhhh."

Most plants won't like the highly oxygenated gravel and will die. My tank is 12x36 so I utilized 3 of the panels. I have always had an undergravel filter and my aquariums. I will be using Koral Filter material from now on. 7in, which is only about half the length of the unit. Most plants won't like the highly oxygenated gravel and will die. I change my filters once a month, so the 12 pack lasts me a year!

"Overall fairly easy."

This filter system doesn't come with everything to you need. I purchased these for an aquarium at school. That's a long time if you knew how nasty that many shrimp and minnows can be! You can run everything on battery backup sockets. But if you don't weekly vacuum it up, it will eventually clog the filter. If you're looking for new filters, go with these. I have been buying these bags for years.

  • Undergravel filter system includes 4 filter plates (each measuring 11.5" X 11.5") with extra large 1 inch adjustable lift tubes.

  • 2 carbon filter cartridges remove odors, and water discoloration by trapping the pollutants in the pores of the carbon.

"Pretty good."

I have a Top Fin 10 power filter and these cartridges fit perfectly. So here is the product size on the boxes that isn't included in the description! It's a pain in the butt to put together the directions don’t do it that well. It was exactly what I needed and fit beautifully. For obvious reasons, don't put them directly above or below a tank. You can cap off the ones you don't want to use. I have used UG filters for many years.

"Good product."

Luckily I'm using powerheads and the weight of it helps hold it in place. We operate a saltwater bait store, dealing in live shrimp and bull minnows. In 20 gallon and under sized tanks these start becoming feasible primary filters. This improves flow and prolongs time between cleaning. It comes with the filter bag, bag frame, and charcoal media all separate. I use this in my filter for aquarium 55 gal. Stop buying those expensive filters, buy this and make your own.

"I love it!"

We rinse the filters 2x a day and they remain in continuous 24 hour operation. Lets start with the amount of filter material you get. Even its quite costly, but it last long. Tank is clean and all my new shrimp are still alive! Small amounts of these bubbles can also help oxygenate the water over time. Ignore all the noise about them being outdated they are a must-have buy it. I just changed it today and the water is crystal clear-- no problems.

"Very easy to do."

I even used some in my Fluval 206 canister filter on my freshwater tank. Why not save some money to put towards more fish or supplies. It eventually begins to decompose into ammonia which is harmful to your fish. Did all of mine The same, never ripped a one and they all fit like a glove. Never use live rooting plants with UG filters. Much better than the cartridges you get when you buy the filters. Lets start with the amount of filter material you get.

"Pretty good."

Especially if you have a take with shrimp or baby fish. Never use live rooting plants with UG filters. Does the job and price was less or at least same as big retailers. This is great for transporting aquarium life from location to location too. I have been buying these bags for years. The first piece does get a bit dirty and usually only lasts a week. Don't believe people who tell you they are dangerous for your tank.

Also work great as filler for canisters and other filters. You may notice this brand is lower cost than some others. The first piece does get a bit dirty and usually only lasts a week. Customizable in terms of media used. You get what you pay for but i had to work on it a lot. Once you do have everything it's a good running system. I also suppose my measuring tape may be off, but I would not think so.

Small amounts of these bubbles can also help oxygenate the water over time. We rinse the filters 2x a day and they remain in continuous 24 hour operation. It was exactly what I needed and fit beautifully. Don't shut it off for more than a few minutes at a time. This is great for transporting aquarium life from location to location too. Even its quite costly, but it last long. Cut slightly oversized, it seems very effective as a particulate filter.

"Great product."

I was having a problem with tiny fish getting sucked into the inlets. In 20 gallon and under sized tanks these start becoming feasible primary filters. The first piece does get a bit dirty and usually only lasts a week. So stock your tanks a few fish at a time. I rinsed and reuse same pad again 3 times and trashed later. You get what you pay for but i had to work on it a lot. I missed it in my opinion these filters are a must have.

"5 gallon enchant tank."

I end up cutting a small 2x3 inch square for each of my media baskets. Don't shut it off for more than a few minutes at a time. Don't get anything smaller than 750VA as you don't want to overload them. It was nicely packaged and is a high quality filter material. Make sure to select the Medium size from Tetra. Just be super careful with the tubes! But a small simple rubber band fixed the issue quickly.

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.

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.
