Replacement Carbon Cartridge for Aqua One AR 850

Key Benefits:

  • Comes in a handy three pack
  • Removes pollutants and toxins, making your water cleaner and healthy.

Made Specifically for:  Aquaone AR850 and AR850T

The Aqua One 4c Carbon and Polymer Wool Cartridge is a disposable filter cartridge pack for use in the Aqua One AquaStyle AR850 aquarium. The Carbon Cartridge form the top layer of the trickle filter. The cartridges should be removed and discarded when blocked with fish waste and debris. This will usually be every four to six weeks.

The Polymer wool layer traps debris while the activated carbon removes odours and clarifies the water. An essential part of the Aqua One trickle-filter system .

Its Huge…..

The Aqua One 4c Carbon Cartridge set is used exclusively in the AR850or Aquastyle 850 as it has been known for the last few years. The Aqua Style 850 has a capacity of 165 liters but the overhead trickle filter provided with the set up extends over the whole back section of the canopy and contains two identical Aqua One 4c carbon cartridges, a complete set of Aqua One 5s sponge sheets and  around 600g of Aqua One Bio Noodles. 

Is the Aqua One 4c the Best Filter cartridge for Aqua Style 850?

It’s important to realise that the Aqua One 4c Carbon Cartridge fulfills three very important functions.

Stage 1: Solids Removal

The first polymer wool layer traps solids and prevents the rest of the filter media being clogged up with them, it also makes sure that your aquarium is free from floating ‘bits’ which would ruin the appearance of clarity we all seek. 

Stage 2: Dissolved Waste Adsorption. 

The Activated carbon granules can now do their work, adsorbing odour causing chemicals, removing yellowness and bonding waste molecules. Activated carbon is clever stuff and incredibly purifying but it works hard and only lasts a short period. You cannot wash carbon out, once all the waste in bonded to its surface that’s it: new cartridge time.

Stage 3: Water Dispersal

Next time you change your Aqua One 4c carbon cartridges turn one over and look at the base….. its made that way to re-disperse the water that has flowed through it to make the best use of the 4c Biofoam and the Bio Noodles underneath that. Without the dispersal tray water would channel through the remaining filter media and lots of surface area would be wasted.

How Long Does the Aqua One 4c Carbon Cartridge Last?

In most well stocked Aqua Style 850 AR850 Aquariums the 4c carbon cartridge will last around four to six weeks, after this time the polymer wool layer becomes blocked and water isn’t traveling through it anywhere near as easily as it should and the carbon granules are exhausted. We suggest you treat yourself and the fish to a new cartridge set.

How Can I get the best value from My Aqua One 4c Carbon Cartridges?

There are two ways to get the best value from Aqua One 4c Carbon cartridges. Makes sure you perform regular water changes, this way the 4c carbon cartridge doesn’t have to work quite as hard to maintain water quality and should last a little longer.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
