 Oase FiltoClear with UVC
|
|
  |
 |
FiltoClear in action with the new dual inlet Oase
Aquamax pump. The second inlet can be used for a
skimmer or as shown to reduce dead spots in the pond. |
|
The Oase FiltoClear range of pond pressure filters have outstanding filtration properties and are very easy to use. Water is pumped through the filter which can then be
directed to a creek or waterfall, even if it is higher than the filter.
The filter works by first passing dirty pond water through an integrated UV
Clarifier to destroy all algae responsible for green water. Dead algae along with all other dirty particles are then filtered out in large sponges which
also double as a biological filter thus returning crystal clear water to the pond.
The filter is then very easily cleaned with the pull of a handle and simple back flush without the need for getting your hands wet. For easy clean information |
- Money back if clear water is not achieved when using the equipment correctly
- Can be placed next to the pond, above or below the water level and can feed a watercourse / stream or waterfall while filtering.
- Mechanical and biological filter and powerful UV clarifier all in one.
- Easy to clean in a few simple steps. For more information
- German made - Quality is of the highest standard.
- Able to filter pond water, ponds up to 30,000 litres in size

Aussie's observations
|
|
Suitable for: Any pond filtration, particularly for waterfalls or streams where water
has to be pumped higher than the filter. |
|
What we liked: The cleaning and back washing system is brilliant, as it does not have to be taken apart that
often For easy clean information. Because the water passes across the UVC before the
filter, the damaged algae spores are caught by the filter rather than being returned to the pond. Typical Oase quality, second to none. |
|
Possible drawbacks: Pressure filters are not ideal for Koi or Turtles, the better option
would be a gravity filter, however, if a waterfall is in use using a single pump for both filtering and waterfall a pressure may be the
best option if a gravity filter box can not be hidden at the very top of the waterfall |

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)
Ways to get help to establish flow
- Fill in one of our e-mail help forms and let us do all the calculations for you
- Give us a call 1800 607 388 for expert advice
- Do it yourself and use our quick reference flow calculator for rough estimate
- Establish the required flow through the filter keeping in mind waterfall** height if any, or long hose**
- Choose a filter from the chart below (Example if your pond requires a flow through the filter of 7,000 litres per hour, the Filtoclear
12000 would give the best result)
- Choose a pump, they are listed below in order of quality and suitability

For waterfalls higher than 500 mm, undersize hose already installed that
can't be replaced or for a long hose length, one of the alternative pumps
listed below my be better suited |
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
- The cage design is turtle shell shaped to attract solids from 360 degrees
- These pumps are designed to run 24/7 year after year
- They have a vortex impeller capable of handling solids without blocking
|
|
**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. |
***** Head over 5m will 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 5 metres (0.5 bar).
So if the filter was mounted 1m above the pond surface, the pressure free outlet must not exceed 6m
There is however another factor in head calculations if long hose lengths are used, see "Friction loss in hose" under
How to calculate your friction loss if your hose will be more than 3m. |
|
Aussie's additional thoughts
Tip 1: When calculating pump flow, always allow at least a 15% flow loss when a 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: Clearpond offer a liquid to prime filter systems, a great way to hasten biological activity. Bio-Starter
Tip 4: How the UVC takes care of algae etc .. When the water passes through the filter, the UV rays from the clarifier disturb the tiny
algae spores that would normally pass through the filter, they then clump them together and they are caught next time through by the foam filters. The UV rays
also kill off disease-causing agents as the water flows through the clarifier. Your pond therefore virtually cleans itself.
Tip 5: 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 6: Head over 5m will 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 5 metres (0.5 bar).
So if the filter was mounted 1m above the pond surface, the pressure free outlet must not exceed 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.

How it all works: Water is pumped into the unit and passes under the UVC lamp into the vortex system (settling zone).
Suspended matter and bio-sludge are moved by centrifugal effect and gravity.
Dirt particles are trapped by the outer surface of the filter sponges before the water flows the entire length of the inner chamber.
Pores of the filter sponges form a large inner surface for micro-organisms to colonize and convert ammonium to nitrate. Other parts
of the filter system are designed to support colonization of anaerobic micro-organisms that reduce nitrate to nitrogen.
A function switch is used when the dirty water is released, (back washed) at the same time the filter sponges are cleaned using a special pumping
handle. The end result is clear / clean pond water.
