Installation guidelines with regard to the

Clear Water Guarantee

OASE guarantees that this system will maintain clear water in a

pond in accordance with the following definitions, installation and

usage guidelines:

Definition of clear water:

Clear water is achieved if the fish or stones at the bottom of the

pond can be seen at a depth of 3,25 feet.

Selecting the right system

Please select the filter system using the following table (selection

criteria: pond size and with/without fish population).

E Biological clarifying

The pores of the filter sponges form a large inner surface

which microorganisms can colonise. The red and blue filter

sponges differ in size and density. This creates zones in

which the water can flow at different speeds. Zones with a

high flow speed (blue filter sponges) favour the colonisation

of microorganisms which convert ammonium to nitrate via

nitride (nitrification). Zones with a low flow speed (red filter

sponges) support the colonisation of anaerobic microorgan-

isms which reduce nitrate to nitrogen (denitrification).

F Water outlet with flow indicator

At the water outlet, the clarified water is fed back into the

garden pond via a pressure hose or a watercourse etc.

G Cleaning connection

When cleaning the filter, a drainage hose can be connected

to the cleaning connection which diverts the dirty water into

a drain or onto a flower bed.

H Function switch

The function switch is used to switch between normal water

discharge into the pond (“Filter“) and the cleaning connec-

tion (“Clean“).

I

Cleaning the filter sponges with the handle function

The filter sponges can be cleaned while the Filtoclear is

operational through hard “pumping” by pressing the cleaning

handle.
