The AquaForte Prime UltraSieve Low XL (73 cm) is the larger and more powerful variant in the Low series and is specially designed for pond installations that require both high flow and limited installation height. With a height of just 73 cm, this model fits into shallow filter pits, while the large screen surface area ensures maximum debris removal.
The 300µm stainless steel screen element removes coarse debris such as leaves, algae, and floating waste before the water reaches the biological filter. This keeps the main filter cleaner, allows it to operate more efficiently, and helps maintain more stable water quality — essential for koi ponds and ponds with high fish stocking densities.
Thanks to its extra-large design and high flow capacity, the UltraSieve Low XL is ideal for installations with multiple bottom drains, skimmers, or powerful pumps. The automatic water level control ensures continuous operation without manual adjustments.
