Oase Filtral Replacement Foam & Media Kits

Oase Filtral Replacement Foam and Media Kits

Correct service media for pre-2019 and current grey Filtral UVC filters

Oase Filtral all-in-one filters changed internal media design, so model name alone is not enough to select the correct replacement. This page separates the complete pre-2019 media kits from the 2019-on grey Filtral 6000/9000 two-foam set.

Parts 13705 and 35836 are earlier complete media kits. They contain coarse and fine foam plus the appropriate mineral and plastic biological media for their listed models. Part 70242 is the current red/blue replacement foam pair for the newer grey Filtral UVC 6000 and 9000; it does not include the earlier loose biological components.

Safe servicing

1. Disconnect the unit from the electricity supply before lifting or opening it.
2. Never operate or view the UVC lamp outside its enclosed housing.
3. Record the original media order and retain reusable cages, trays and covers.
4. Rinse established media in removed pond water; rinse new media in clean water without detergent.
5. Inspect the impeller, fountain outlets, quartz sleeve, lamp and seals during the same service.
6. Restart the unit fully submerged as instructed and confirm normal flow before leaving it unattended.

A complete media change temporarily removes much of the mature biofilm. Feed lightly and use suitable pond-water tests for ammonia and nitrite while the filter recolonises. Browse our filter-spares range for further model-specific service parts.

Frequently asked questions

Which kit fits a Filtral 6000?

It depends on generation. Use 35836 for the pre-2019 unit and 70242 for the current 2019-on grey Filtral UVC 6000.

Does 70242 include biological media?

No. It is the red/blue foam pair for current 6000/9000 units. The older complete kits include additional media.

Can I use 13705 in a Filtral 5000?

No. Part 13705 is the smaller pre-2019 2500/3000 kit; part 35836 covers the larger pre-2019 family.

Should I discard all old media?

Replace physically failed material, but preserve healthy mature media where the filter design permits. Avoid washing useful biofilm in chlorinated tap water.

How can I identify the generation?

Use the data plate, original product code, casing shape and colour. Send us clear photographs if there is any doubt.
