KOI POND 1 BAG FIBREGLASS SAND FILTER ULTRAZAP

Product Description:

The UltraZap 1 Bag Fibreglass Sand Filter is a compact, durable mechanical filter designed for koi ponds up to 5000 litres. Built from robust woven fibreglass, this filter offers strength and simplicity, making it ideal for smaller pond setups requiring reliable solid waste removal.

Water is pushed upward through the sand bed, a process that temporarily suspends the particles, increasing surface area and encouraging the breakdown of waste compounds. While traditional sand filters offer efficient solid filtration, it’s important to note their limitations when used in fish ponds. Unlike biological filters, sand filters do not support the aerobic bacteria needed for full biological filtration.

Regular backwashing is required—often daily—to prevent clogging from koi waste, debris, and algae buildup. Sand filters also require more pump power, which can mean higher energy usage compared to bubble bead filters. However, when used correctly as a pre-filtration stage before UV or biofilters, the UltraZap sand filter plays a key role in maintaining water clarity.

Best suited for pond owners who want robust mechanical filtration before advancing to more complex biological systems, the UltraZap 1 Bag model offers straightforward installation and dependable debris removal.

FAQs:

Can I use this as my only pond filter?
No, it is best used as a mechanical pre-filter before a biological or UV system.

How often should I backwash the filter?
Typically once a day, depending on pond load and debris levels.

Is this filter energy efficient?
It requires a stronger pump than bead filters, resulting in slightly higher energy use.

What size pond is it ideal for?
Koi ponds up to 5000 litres.

Does this filter support biological filtration?
No, sand filters operate in anaerobic conditions, which are not suitable for beneficial bacteria growth.
