Fluval Edge Pre-Filter Sponge, Replacement Aquarium Filter Media, A1387

UPDATE: I have been using these Fluval pre-filters for the past few years now, and they really are quite useful in easing the load on an aquarium filter's mechanical filtration. I have these pre-filters on most of my planted aquaria, and I clean them once a week, since the flow is noticeably slower by that time. The fact that the water flow in an aquarium filter can be down to a trickle within a week's time, after installing one of these pre-filters on its intake, should give the reader an idea of their superb filtering ability. These filters are also available on Amazon.com in 3 packs for about $4.88, including shipping. This is the best deal that I have seen on these pre-filters. The reader should also find of interest that while these pre-filters are sold for the Aquaclear 20 filters on the Fluval 6 & 12 gallon Edge aquariums, they can also be used on the intakes of most filters whose diameter is up to a half inch, since these pre-filters will stretch a bit. The key is to clean them weekly so that they maintain good water flow. Until you have used a pre-filter, whether it's the Fluval or one from another aquarium filter manufacturer, you have no idea how beneficial these pre-filters are in easing the job of the mechanical filtration in your aquarium filter. * Notation: In regard to Aquaclear filters, this author also uses an Aquaclear 50 and Aquaclear 70 as dedicated mechanical filters for fine filtering (water polishing) the water in my planted aquaria. I use the AC 50 on the small tanks and the AC 70 on the larger ones, and just move the filters from one tank to the next, after they have been micron filtered. I use the foam block on the bottom of the basket for these filters, with a 25 micron filter pad from Marineland atop this foam block, and an 0.5 micron pad from a wine manufacturer sitting atop the Marineland micron filter. This gives these filters the ability to polish an aquarium's water column as well as a dedicated diatom filter, like a Vortex D-1 or XL; both of which I also have. This setup is for those fishkeepers who don't want to make the investment in a diatom filter, and have a spare Aquaclear filter laying around. Earlier... As a fishkeeper, I have quite a few guppies that are constantly reproducing, as well as a pair of Panda Coryadoras who spawn regularly, producing fry. In the past this led me to purchase a sponge filter that took up quite a bit of room in my *guppy tank. * By the time my Panda Cory's started to spawn, I had already been using the Fluval pre-filters in their aquarium. The small size of the fry also forced me to turn off the hob filter that I was using at the time in my guppy tank, in order to prevent guppy fry from being sucked into its intake. Then I saw these Fluval Edge pre-filters online, and having recalled reading that the Fluval Edge 6 gallon aquarium uses an Aquaclear 20 filter, decided to purchase a few of these pre-filters to install on the Aquaclear 20 filters I was using on my guppy tanks. They have worked out extremely well, reducing the amount of detritus in my Aquaclear filters, while being much quicker to clean. You simply slip the pre-filter off the intake of the Aquaclear filter, rinse it under some tap water, and reinstall it. The entire process takes less than a minute. As such, this author highly recommends the Fluval Edge pre-filter for use on the aforementioned Aquaclear hob filters, as well as any aquarium filter intake tube that has a diameter of 1/2" or less.

Immediately solved my water turbulence issue on the betta tank. We have an ecocube aquarium which I had to replace the pump on and the new one has a higher flow rate. This pre filter fit perfectly over the output to completely diffuse the water so there is no more turbulence and betta is happy.

I purchased two 3.5 gallon tanks from PetSmart; however I wanted to use one as a hospital tank with minimal flow for any potentially sick fish. Although this pre-filter is designed for use with another filter it fit perfectly on my hospital tank filter. It slows the flow well and doesn’t suck up the fish. I ended up using another one of these over the intake in my 5 gallon shrimp tank. Again it fit perfectly and worked as intended. Make sure you routinely squeeze it out in your old aquarium water because it does get clogged due to the fine filter material.

These pre sponges work just fine overall but are a little bit too short for certain filters. I had one on a filter with a long inlet tube and I had trouble covering the bottom of it with the sponge. There’s always the risk of small fish or shrimp getting sucked into the filter. As long as it fits your tubing, it should be fine

I bought these to cover the intake of my 10 gallon tank's "hang on back" filter for my betta fish. I have read horror stories of betta fins being sucked into the intake of filters and torn all up, so I wanted to prevent that for my little guy! This sponge fits perfectly over the slotted intake, and also catches algae well. When I'm doing water changes and tank cleanings, I just rinse it in water to remove any algae and put it back on. Works very well.

I bought two of these because my Aqueon Whisper 10 is too strong for my fish. One I cut the bottom off of, and the other I left intact. I put the the cut sponge onto the Aqueon filter suction tube first, and then the uncut one (with a closed bottom) below. This covers the entire suction tube of the Aqueon filter. This, plus a plastic bottle for baffling the outflow of the Aqueon make my aquarium safe even for the itty bitty ghost shrimp. My betta's tail is no longer getting sucked into the filter. Oh, I have a rock just under the filter tube so that a power outage won't cause the sponges to fall off and float away. They will slide down a bit if the power stops, but they shouldn't fall off entirely. Don't be afraid to use these on non-Fluval filters. If the tube will fit, then this will help your delicate or tiny fish.

I love how small these are..perfect for my 3.5 gallon tanks...even my 5gallon tank it works well with. They help with bacteria growth and keeping fins of my bettas and shrimp safe from the intake. The packagees were very ruff, the boxes busted open...good thing it was sponges inside. I also was not happy with where the driver left my package...I have requested that they be put in front of my door, but the driver chose to leave it at the entryway to the whole apartment building...if I had not seen it laying there and looked I wouldn't of known it was mine. Children run in and out of this complex and might not if known not to touch it. I'm just glad I was waiting on it and when it said delivered...I went searching.

I have a fluval 407. This product is small and fits perfectly when the nozzle of the filter is removed. This product clogs up quick and the filter sucking power is reduced then it stops the filter from pushing out water. I thought my filter was broken until I removed the sponge the water started flowing again. This is not good for a cichlid tank However it would be good for a tetra or molly or guppy tank. Price for this sponge is too much. Should be under a dollar or you can buy a coarse sponge cut it out and attach it yourself to the nozzle of your filter would be a lot cheaper.

Efficace

Passa perfekt på aquaclear 20 och ser väl så bra en försvamp nu kan göra, rekommenderas ifall man har räkor,yngel eller fiskar med stora fenor

Good quality pre filter sponge and holes are small enough to allow water to pass through but not big enough to allow detritus to pass through. 10/10 functionality.

Good but pricey for the size!
