The OASE Filtoclear 31000 is a pressure filter with a built-in 60W UVC clarifier, suited to large ponds with a flow of up to 17,000 L/h. It combines mechanical and biological filtration across layered filter foams with UVC treatment, so green water, algae and pathogens are dealt with in one compact unit.

It sits beside the pond, in the garden or in a pump room, and can be buried up to the lid. A pump in the pond feeds the filter and clean water returns to the pond through hose. We recommend these filters often, even at their higher price, because over many years we have found them reliable, effective and simple.

Features & Benefits

• Patented cleaning mechanism: pull the handle to squeeze the foams clean from the outside, with no need to open the filter or touch the water.
• Two-way valve sends dirty water to the pond or to waste, such as a garden bed, after cleaning.
• Built-in 60W UVC clarifier keeps green water at bay and reduces harmful bacteria and pathogens.
• UV lamp can be changed while the filter is running, with no need to remove the quartz sleeve.
• OASE bypass technology keeps water flowing and helps prevent clogging.
• Tough plastic housing with a metal clamping ring and lever for safe, easy opening.
• Blue indicator light on the lid shows when the UV lamp is on.
• Optional stone-look FiltoCap cover blends the filter into the garden.

Specifications

How to Use

• Pair it with a solids-handling pump rated up to about 17,000 L/h. We recommend pairing it with the OASE Aquamax Classic 17500.
• For hose, 50mm flexible pond hose is recommended, or 50mm PVC for a permanent installation. 38 to 40mm hose can be used if needed.
• Position the filter beside the pond, buried up to the lid if you wish, and connect the pump to the inlet and the outlet to the pond.
• To clean, pull the handle to squeeze the foams, then flush the dirty water to waste through the two-way valve.
• Replace the UV globe every 12 months. It may still light up after that, but it is no longer effective against algae.

Recommended For

• Ponds up to 10,000L with no fish, 6,000L with goldfish, or 4,500L with koi.
• Pond keepers who want an easy-to-clean filter and UV clarifier in one unit.
• Ponds with green water, or those that get plenty of sun.
