Edge Pre Filter Sponge

Good but pricey for the size!

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.

Costoso, pero funciona, se estira bastante, lo compre para mí fluval 107 y que no se aspire a las crías de gambas.

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.
