        Water Dargon Pond pressure filter
Water Dragon Filter instillation

The pump sitting in the pond pushing water through the Pressure filter either up to a waterfall or directly back into the pond. Waste water from the backwash hose can be placed into the garden, the filter can either be buried up to the lid or simply sit on the ground.

Aussie's observations

Water Dragon's filters are suitable for: Any pond where filtered water is required. In particular when water is to be pumped to a higher level such as a waterfall or feature. We recommend a gravity filter when Koi or turtles are present
What we liked:  The solid Australian design. The backwash is a true backwash system, not like all of the other filters on the Australian markets. The handle is easy to squeeze the foams, the only others that do this are double the price. The good wattage of the UV lamps. The LED indicator light on top, safely see when the lamp is working day or night. Every model has a back wash system that is very easy to use. Great value for money.
Less than ideal: Pressure filters in general are not ideal for Koi or Turtles, the better option would be a gravity filter, However, if a waterfall is in use with a single pump for both filtering and the waterfall, a pressure filter may be the only option, other than using 2 pumps.

Consider mix and matching different filters to better fit your pond and pocket .... Any of the above filters can be joined together using a tee and hose. Example:  A 8000-UVC with a 12000-UVC gives you a 20000 
The other advantage is that if your pond is is enlarged or if you fish stocking increases you can just simply add a filter

Filter selection

To choose the ideal filter for any pond you must first know the correct environmental flow to maintain ideal water quality for your pond. (Please remember that the pond size alone does not determine the filter or pump size without first taking into account the many environmental and physical factors) 

3 ways to get help
to establish flow

  1. Fill in one of our e-mail help forms and let us do all the calculations for you

  2. Give us a call 1800 607 388 for expert advice

  3. Do it yourself and use our quick reference flow calculator for rough estimate

  • Step one: Establish the required flow through the filter keeping in mind waterfall** height if any, or long hose**

  • Step Two: Choose a filter from the chart below (Example if your pond requires a flow through the filter of 3,400 litres per hour, the Pressure Filter 8000 would give the best result)

  • Step Three: Choose a pump, they are listed below in order of quality and suitability

Recommended flow through the filter - litres per hour


4000 8000 12000
Minimum Flow 1,200 2,000 3,000
Ideal Flow - See hint 4 below 2,000 3,500 5,000
Maximum Flow - See hint 4 3,000 4,500 6,000

What makes a pump that is specifically designed for sending water to a filter (such as the pumps above) superior to a multi purpose pump such as Pondmate
1) The cage design is turtle shell shaped to attract solids from 360 degrees   2) These pumps are designed to run 24/7 year after year   3) They have a vortex impeller capable of handling solids without blocking

Other workable pumps

Pondmate 2400## Pondmate 4800# Pondmate 6000DWP#


**Special note, if using a waterfall or a long hose between pump and filter the pump will need to be larger to allow for the reduced flow caused by the head (pumping height, and/or hose length)   If in doubt Fill in one of our e-mail help forms and let us do all the calculations for you.
# A little under size for some pond sizes, but would work if the pond were smaller than the filters maximum volume rating.
## This pump is a little too strong, unless a waterfall over 1m is in place. However, you can never have too much pond flow, so, by releasing water back into the pond through a "Tee" and flow valve added circulation is provided for the pond.

 Aussie's additional thoughts
Tip 1:
When calculating flow,  always allow about a 15% flow loss when a pressure filter is used.
Tip 2: Place the pump at the opposite end of the pond to the water return, and in the deepest part of the pond.
Tip 3: Interpet offer a powder to prime filter systems, a great way to hasten biological activity. Interpet Bio start .

Tip 4: Within reason the slower the water passes over the UV lamp and through the filter the better the result. However, you can never have too much pond flow, so, by having a slightly oversize pump and releasing water directly back into the pond or on to a feature or waterfall through a "Tee" with a valve (tap), added circulation is provided for the pond.

Tip 5: Pump - maximum pumping head. The pump supplying the filter must not have a pumping head exceeding 4m (0.4 bar)  Head over 4m could damage the filter and could even burst the container. On the other hand a pump with inadequate head may not provide enough flow through the filter
In a nut shell ....The height difference between the filter lid and a pressure free outlet must not exceed 4 metres (0.4 bar). So if the filter was mounted 1m above the pond surface, the pump must not have a maximum pumping height in excess of 5m. Or if mounted 2m above the surface of the pond, the pump must not have a maximum pumping height in excess of 6m.
There is however another factor in head calculations if long hose lengths are used, see "Friction loss in hose" under How to choose your pump / filter  if your hose will be more than 3m
