JUWEL bioPlus Fine Filter Sponge - XL

JUWEL bioPlus Fine Filter Sponge - XL is a fine biological filter sponge for the Bioflow 8.0 and Bioflow Jumbo filters.

Key Features

• Fits the Bioflow 8.0 and Bioflow Jumbo filters: Order by the filter, not by the tank. This is the XL size, and the sizes are not interchangeable.
• Where the bacteria live: A finer sponge polishes the water and carries bacteria as well. It clogs sooner than coarse, so it sits behind it in the stack.
• How this one is handled: Biological media. Rinse it in tank water and put it straight back; the bacteria living in it are the point of it, and they do not survive the tap.
• One part of a stack: A Bioflow runs several media together. Changing them all at once restarts the tank's cycle, so stagger them.

Ordering The Right One

• Order by your filter model, not by the litres of your aquarium. The letter on the box is the Bioflow it fits, and the sizes do not interchange.
• If you are unsure which Bioflow you have, tell us which JUWEL aquarium it came with and we will work it out and confirm before we dispatch.

Looking After Filter Media

• Never rinse biological media under the tap. Dubai tap water is chlorinated, chlorine kills the bacteria you are trying to keep, and those bacteria are the entire value of the sponge. Rinse it in a bucket of tank water.
• Never change all the media at once. Swap one part and leave the rest, so the bacterial population survives and the tank does not restart its cycle.
• Mechanical pads clog and get replaced. Biological sponge and ceramic get rinsed and go back in. Chemical media are used up and then do nothing.

Good To Know

• Rinse it in tank water, never under the tap, and expect it to last a long time. A sponge does not need replacing just because it is brown.
• Fits the Bioflow 8.0 and Bioflow Jumbo filters. Tell us your aquarium model if you are not sure which Bioflow you have.
• Stagger your media changes. Replacing everything in one go is the commonest way a settled tank suddenly reads ammonia again.
