The guarantee is invalidated if the installation instruc-
tions in the instruction manuals are not complied with,
or in the case of wrong system selection, or if pond care
products from other manufacturers are used, particu-
larly if pond care products containing copper are used,
or if the customer’s behaviour otherwise is in violation
of the customer’s obligations. Comply with the service
and maintenance instructions in the instruction manual.
Frequent causes for unclear water
• Failure to replace parts subject to wear, e.g. UVC bulb
or filter foams
• The height difference between the water surface and
the highest point in the pressure system is greater
than 1 m (assumed value in the OASE selection tables)
• Pressure losses due to excessive hose lengths or a
hose diameter that is too narrow
• Missing inlet barrier (capillary barrier), surface water
flushes mud and/or fertiliser (nitrogen, lawn fertiliser
etc.) into the pond from the garden
• Over-intensive feeding of fish generates nutrient
loads in the pond
• Incorrect placement of the pond results in imbalance
(e.g. too much sun, too much shade)
• Faulty mixing of the pond water, i.e. deficient circu-
lation
The guarantee applies for 3 years from the date of
purchase from the OASE dealer (first purchase, not for
resale of the new product). A directory of OASE dealers is
available at
In the case of a guarantee claim the dealer refunds the
purchase price paid for the product against submis-
sion of the original purchase receipt and return of the
defective product, if OASE has previously accepted the
guarantee claim. More extensive claims arising from the
Clear Water Guarantee do not exist.
The legal guarantee rights of the purchaser remain unaf-

Clear Water Guarantee conditions from OASE:
OASE guarantees clear water in the pond to all purchasers
of an OASE filter system, if the system is used properly in
accordance with the selection table, if the system is set
up properly in accordance with the set-up instructions,
and in compliance with the instructions in the opera-
ting manual, and in compliance with the instructions for
achieving clear water in the pond through the addition of
OASE filter starter bacteria in the defined scope.
Clear water means that fish, plants, or rocks on the pond
floor are recognizable to a pond depth of 1 m below the
pond surface. Ponds with string algae are not considered
to be unclear, as scarcely any suspended substances are
formed. Pond water is not tap water. Turbidity and colou-
ration are always present and are also natural, and these
conditions exclude a guarantee case.
The Clear Water Guarantee is granted exclusively for
ponds in the conventional sense of the term. A pond
is an artificially created body of water made of liner or
in a preformed pond with minimum planting of 1/3 of
the water surface and is exposed to sunlight for 4 to 6
hours a day. The location of the pond is 4 m away from
deciduous trees and/or conifers. For the first use and
every new use in the spring the application of OASE fil-
ter starter bacteria is prerequisite. It can take up to 6
weeks until the pond is clear, depending on the burden
of the pond. The filter works mechanically and biologi-
cally. Settlement of microorganisms is required for biolo-
gical cleaning. Consequently the Clear Water Guarantee
assumes that the pump, and thus the filter system, is
operating 24 hours a day during the pond season (appro-
ximately from March to September). Excessive cleaning
prevents adequate formation of microorganisms in the
filter foam. If cleaned too infrequently the filter sponges
cannot absorb any more pollutants, or they can only do
so if the flow-through rate is significantly reduced.
Prior to submitting a guarantee claim the customer is
obligated to report the deficiencies determined via the
OASE Service Hotline (see below). After logging the fault,
OASE will provide assistance for correction of the fault. If
help cannot be provided on-site, or if the help does not
bring the desired success, the customer must then in-
form the Hotline specified above of this situation. Then,
if OASE cannot suggest any other remedy possibility that
should be attempted, the customer has a claim for pro-
cessing of the guarantee through the dealer, if in all other
aspects OASE affirms/determines that the prerequisites
of the guarantee are satisfied. Otherwise the dealer has
a last opportunity to attempt to implement the consul-
ting.
