Description

Keep your Fluval U2 Underwater Filter working effectively and help to control green water and algae growth with Fluval U2 Poly/Clearmax Filter Cartridge. Fish waste, uneaten food and other organic matter can build up in your aquarium water, causing algae growth and increased phosphate, nitrite and nitrate levels. Raise these levels too much, and they can be harmful to fish. This filter cartridge helps to absorb and trap these pollutants, protecting your aquarium and those who call it home. Designed for the Fluval U2 Underwater Filter, Fluval U2 Poly/Clearmax Filter Cartridge supports crystal clear water, helps to control odor and works to reduce overall aquarium maintenance.

Key Benefits
  • Helps control green water and unsightly algae growth for a clear, beautiful tank.
  • Chemical filter media helps to absorb and trap phosphate, nitrite and nitrate.
  • Encourages crystal clear water, helps to reduce odors and encourages the ideal conditions for fish and plants.
  • Helps to reduce overall aquarium maintenance, so you can enjoy your tank more and worry about it less.
  • Convenient two-pack gives you one cartridge for now, and one for later.
Precautions

HAZARDS TO HUMANS: Always disconnect appliances in the aquarium from the electrical supply before placing hands in the water, before putting on or taking off parts, and whenever the filter equipment is being installed, maintained or handled. Following a routine maintenance schedule will result in a healthier aquarium and extend the life of the filter. Fluval filters have been designed to facilitate these tasks as they can be done within a matter of minutes. For best results, please follow our maintenance schedule recommendations.

Instructions
  • Replace Alternate Foam Pads every 3 - 6 months.

  • Do not replace all Filtration Cartridges at the same time. Alternate Filter Cartridge changes so that some older cartridges remain in use. This ensures the re-seeding of beneficial bacteria, so that colonies discarded with older cartridges will be replaced by vigorous new ones. To enhance bacterial action, pour a dose of biological aquarium supplement onto your Filter Cartridges each time you change the media.

  • Unplug the power cord.

  • Open the filter cover (to make the operation easier and in case the filter is positioned under an aquarium frame, tilt the filter forward until it stops but make sure there is enough electrical cord to allow the filter to pull forward).

  • Slide the Foam Cartridge Frames out of the filter body. Keeping them vertical to avoid releasing the debris collected inside the debris receptacle. Place them in an empty bucket.

  • Remove the poly/carbon cartridge from the cartridge frame.

  • Remove the foam. Rinse the debris receptacle and the foam pads using water taken from the aquarium or replace one of the foams following the recommended replacement schedule. Do not use tap water as this will kill the beneficial bacteria in your foam. Note: Never use soap or detergents as these products could be harmful to the inhabitants of your aquarium.

  • Replace the foam pad. Make sure the foam is positioned behind the tabs on the sides of the frame.

  • With the carbon side facing out, re-insert the poly/carbon cartridge by inserting the lower end of the cartridge into the lower end of the cartridge frame then snapping the top side of the cartridge under the two tabs on the top side of the frame. Do not press too hard, as the cartridge must sit on the top of the tabs on the sides of the frame. Hint: For best results, replace 1 poly/carbon cartridge every 2 weeks.

  • Slide the BioMAX cartridge out and place it in the sink or bucket.

  • Pull open the tab on the side of the cartridge, opening the cover. Rinse the BioMAX with aquarium water, never tap water, or replace half the quantity every 5-6 months. Never replace all the BioMAX nodes at one time, as valuable colonies of beneficial bacteria would be lost.

  • After rinsing, put the BioMAX back in the cartridge and close the cover. For best results, completely fill the cartridge.

  • Re-insert the Foam Cartridge Frames into the filter with the poly/carbon pad facing inwards. Re-insert the BIOMAX cartridge into the filter making sure to properly align the hole at the bottom of the cartridge directly on the top of the impeller opening. Close the filter cover and if required, snap the filter body back into position on the filter bracket.

    Clear filter

    By LDIPDX on Nov 7, 2020

    Wanted to clarify to other readers... This filter is not a carbon filter and does not claim to be, granted there is a small amount of carbon inside the filter but this is a clearmax filter and not a poly/carbon filter. I use one of these on one side of my U2 power filter and a poly/carbon filter on the other side and it works just great, water is crystal clear all the time and no algae.

    Disappointed

    By Kemi on Sep 28, 2020

    I got these thinking they were the same, or at least as good, as the other poly cartridge for my fluval and they're not. There's hardly any carbon compared to the others ones having one side be carbon, and wear out very quickly.

    Great price....not carbon filter

    By Flyers on Jul 22, 2018

    I thought these were the correct “carbon” filters for this Fluval filter but there’s not even a tablespoon of carbon in the ones I bought. I’m going to buy a box from nearest pet store and compare but I’m pretty sure these ones are defective - all 5 boxes
