Oase BioSmart 36000 Pond Filter

Oase BioSmart 36000 Pond Filter

The nine-foam filter without a pump or UVC

The Oase BioSmart 36000 Filter is a flow-through pond filter. The filter-only BioSmart 36000 provides a nine-foam mechanical and biological stage. A circulation pump and UVC clarifier are separate, so it can be matched to the equipment already on your pond.

A free-flowing return to the pond

Water is pumped into the filter, passes through the foams and leaves through the gravity outlet. The foams trap suspended solids and provide surfaces for biological filtration. A UVC works on suspended green-water algae; it does not replace the foams or remove settled sludge.

Install the filter on a firm, level base with its outlet positioned to drain freely back to the pond. This is not a sealed pressure filter for pumping clean water uphill from the outlet. Keep the return large enough and free of restrictions, and leave access to the lid, cleaning handles and drain.

Choose the rating for your fish load

The 36000 model name is not the same as the suitable volume for a stocked koi pond. Oase gives separate ornamental, general fish and koi ratings, shown below. Feeding, fish size, sunshine and the amount of waste entering the filter all influence the sensible choice.

Cleaning and replacement parts

The cleaning handles squeeze accumulated dirt from the foams, and the sludge outlet lets you discharge that dirty water. Check the dirt indicator and the actual pond conditions to decide when cleaning is needed. Allow a suitable waste route before fitting the filter rather than trying to carry dirty water away afterwards.

For replacement media, use the matching BioSmart replacement foams and select the correct model and colour. Where a UVC is fitted, isolate it before servicing and match replacement lamps and quartz parts to the actual Vitronic label.

If you need the circulation pump and UVC as well, compare the BioSmart 36000 pump and UVC set. The BioSmart range shows the other sizes and set combinations.
