UltraZap Bio Blocks 5L

UltraZap Bio Blocks 5L

UltraZap Bio Blocks 5L is a pond biological filter media, sold as a 5 litre (1.3 gal) pack, designed to give your pond filter a surface for biological filtration without the clogging problems common to other media. It suits pond keepers who want efficient, low-maintenance filtration for a clean, healthy pond environment for their aquatic life.

Key Benefits

• Delivers superior biological filtration in ponds
• Non-clogging surfaces: the broad spaces within each bio ball are engineered intentionally to thwart clogging
• Designed to hold an edge over other biological media alternatives thanks to this open construction
• Helps maintain efficient water filtration and supports a clean, healthy pond environment
• Works with a pre-filter, which removes the elements that could cause blockages, so clogs are made virtually non-existent

How to Use

• Pass the pond water through mechanical filtration (a pre-filter such as filter wool or sponge) first, before it reaches the biological filtration stage
• This sieves out larger, potentially clogging particles early, leaving the bio balls to work at peak efficiency
• Place the bio balls in the biological stage of your pond filter, after the pre-filter

Suitable For

• Pond filtration systems that use biological media
• Pond owners who want trouble-free, efficient water filtration for their aquatic life

Compatibility

Designed to be used downstream of mechanical pre-filtration such as filter wool or sponge.

What's Included

• 1 x UltraZap Bio Blocks (Pond Bio Balls), 5 litres (1.3 gal)

Frequently Asked Questions

What do UltraZap Bio Blocks do in a pond filter?
They provide biological filtration media for your pond, with open, non-clogging surfaces designed to keep water filtering efficiently.

Why are these bio balls less likely to clog?
Each ball has broad spaces engineered intentionally to prevent clogging. Combined with a pre-filter, the particles that could cause blockages are removed before the water reaches the media.

Do I need a pre-filter?
Yes, it is strongly recommended. Water should pass through mechanical filtration, such as filter wool or sponge, before the biological stage so larger particles are sieved out first.

Are Bio Blocks and Pond Bio Balls the same product?
Yes. The product is referred to as both UltraZap Bio Blocks and UltraZap Pond Bio Balls (Blocks).

What quantity comes in the pack?
The pack contains 5 litres (1.3 gal) of media.
