Frequently Asked Questions

The recommended flow rate for the K1 MicroBead filters is to circulate the total pond volume through the filter every 2-3 hours, so if you have a 20000 litre pond, circulating 7000 and 10000 litres per hour would be ideal.

No, one of the great advantages of the K1 MicroBead filters is they produce very little back pressure, so you can use a lower wattage pump saving you money!

Whilst a pre-filter such as the Cetus Sieve will reduce the cleaning frequency of the K1 MicroBead, it is not a requirement.

No, the Cetus will need to be gravity fed to install before a K1 MicroBead filter.

Yes, the K1 MicroBead are designed to be used with or without a pre-filter.

Yes, the K1 MicroBead filters are ideal for use on skimmer lines.

The maximum flow is dictated by the pond size, there is no maximum flow rate specified. We recommend passing the pond volume thorough the filter every 2-3 hours, so for a 20'000litre pond the recommended flow would be 10'000lph

Typically in summer the filter will require cleaning once or twice a week, however every pond if different and cleaning requirement will vary depending on stocking density, exposure to sun and other variables.

1. Insufficient filtration time
2. Low flow
3. Dirty filter requires rinsing and backwashing
4. Pump has blocked.
5. Inlet line is blocked.
6. Pump is not primed.
7. Incorrect water chemistry. Check pH and other water readings. Check UV is working correctly (replace UV bulbs older than 6 - 12 months).
8. Clogged or channelled media. Perform an extra long rinse and backwash.

Too much algae. Excessive water flow and pressure. Check pump size. Overloaded with fish. Excessive feeding. Filter blocked through calcium.

Scoring or jamming with foreign matter or debris. If this condition persists after rinsing, disassemble the valve to clear. Continued operation may result in leaking due to damage to the multi-port valve (spider gasket). See dealer or installer.

  • Switching the Air Blower ON and OFF 2 or 3 times and performing multiple rinses can free up media.
  • Performing a backwash prior to following the cleaning instructions can free up the media.
  • Operating the filter on re-circulate will determine if the restriction is in the filter.
  • If you don’t succeed when following the two points above, switch off the pump, isolate and drain the filter. Manually drain the filter, remove the lid and inspect the inside of the unit. The media may need to be removed and cleaned.
