OASE Filter Selection Guide — Which Family Is Right for Your Pond?

OASE's five filter families serve different pond sizes, installation types, and performance tiers. Fish load reduces effective ratings significantly — size up for koi ponds.

Filter Family Type UV Included Max Pond (no fish) Price Range Best For
Filtral UVC In-pond all-in-one ✅ Yes ~400 gal $215–$276 Small patio ponds · no plumbing · simplest setup
BioPress UVC External pressure canister ✅ Yes ~600 gal $187–$338 Small external filter · compact · easy backwash
BioSmart Open-top gravity filter ❌ No ~2,500 gal $264–$463 Medium water gardens · good bio capacity · value
FiltoClear 3rd Gen External pressure + UV ✅ Yes 3,400–8,200 gal $535–$765 Medium-large ponds · Easy-Clean backflush · inline
BioTec ScreenMatic² Gravity flow-through + auto screen Optional Bitron C 18,000–39,000 gal $1,130–$4,615 Large koi ponds · automated · Clear Water Guarantee eligible

ⓘ Fish load cuts effective pond ratings significantly. For koi ponds, use approximately half the listed "no fish" volume as your sizing baseline. Call (765) 508-4352 for sizing guidance specific to your stocking level.

The OASE BioTec ScreenMatic² — The Most Advanced Consumer Koi Pond Filter Available

The BioTec ScreenMatic² is in a different class from any other filter in this collection — or in most dealer catalogs. Here's what makes it extraordinary:

Automated 300-Micron Self-Cleaning Screen
An intelligent sensor detects debris buildup on the 300-micron mechanical screen. Every 15 minutes (or when needed), it automatically triggers a cleaning cycle that sweeps debris into a removable tray — no manual intervention required for the mechanical filtration stage. This is the equivalent of a rotary drum filter (RDF) that normally costs tens of thousands of dollars in professional koi installations — available at consumer scale.
Multi-Zone Biological Filtration
Three distinct densities of biological foam provide staged biological filtration — progressively finer media harbors different beneficial bacteria strains that collectively process ammonia, nitrite, and nitrates. The foams clean directly inside the filter in pond water (not tap water) to preserve bacterial colonies. Double-sealed motor and reinforced screen ensure extended service life. Sludge drain valve removes accumulated waste with minimal mess.
OASE Clear Water Guarantee
When the BioTec ScreenMatic² is paired with an OASE AquaMax Eco pump AND an OASE Bitron C UV clarifier (which bolts directly to the ScreenMatic inlet), the system qualifies for the OASE Clear Water Guarantee — clear water visible to at least 3 feet depth. This is OASE's commitment that the correctly specified and operated system will deliver the clarity it promises.
Three Sizes: 18K / 24K / 39K Gallons
BioTec 18000 ($1,130): up to 18,000 gal without fish, ~9,000 gal koi pond. BioTec 24000 ($1,414): up to 24,000 gal without fish, ~12,000 gal koi pond. BioTec 39000 ($4,615): up to 39,000 gal — professional scale. Important: BioTec 18000 and 24000 ship by standard freight; BioTec 39000 requires freight delivery with scheduling. Call us before ordering the 39000.

OASE Pond Products FAQs

What is OASE and why is it considered a premium pond brand?
OASE was founded in Westfalia, Germany in 1949 and has become the global leader in water gardening technology. Over 75 years of engineering development shows in the detail: quieter pump operation, precise sealing surfaces, multi-zone biological filtration, and self-cleaning filter mechanisms that reduce maintenance while improving performance. OASE is now part of the OASE Group, which includes Atlantic Water Gardens — the combination that produced the Atlantic-OASE Clear Water System. OASE is the correct choice when you want engineering precision, long service life, and performance that holds up through peak summer conditions with fish loads that would overwhelm ordinary filtration.
What are the five OASE filter families and how do I choose between them?
Filtral UVC: submersible all-in-one for small ponds under 400 gallons — no external plumbing. BioPress UVC: compact external pressure canister with UV for small ponds up to ~600 gallons — easy backwash. BioSmart: open-top gravity filter for medium ponds up to ~2,500 gallons — strong biological capacity, no UV. FiltoClear 3rd Gen: external pressurized canister + UV with Easy-Clean backflush technology for ponds up to 8,200 gallons — the mainstream OASE filter choice. BioTec ScreenMatic²: automated gravity flow-through filter with self-cleaning 300-micron mechanical screen for large koi ponds up to 39,000 gallons — OASE's flagship. Choose by pond size and fish load, sizing up when stocking is heavy.
What is the OASE BioTec ScreenMatic² and what makes it different from other filters?
The BioTec ScreenMatic² is a gravity-return flow-through filter with a unique automated self-cleaning mechanical screen. An intelligent sensor detects debris on the 300-micron screen and triggers an automatic cleaning cycle approximately every 15 minutes — depositing coarse debris into a removable tray without any manual intervention. This self-cleaning screen is the equivalent of a rotary drum filter (RDF) used in professional koi facilities, brought to consumer scale. The filter then provides three-zone biological filtration using different densities of foam media. The combination qualifies for the OASE Clear Water Guarantee when paired with an OASE AquaMax Eco pump and Bitron C UV clarifier. Available in 18,000, 24,000, and 39,000-gallon ratings.
What is the difference between OASE Waterfall pumps and AquaMax Eco Premium pumps?
OASE Waterfall pumps (1,650–8,000 GPH) are optimized for high-flow waterfall, stream, pondless, and skimmer-to-filter applications — the pump sits in a reservoir, sump, or skimmer housing and pushes water to a waterfall or external filter via a delivery pipe. The AquaMax Eco Premium series (2,500–5,500 GPH) uses a synchronous electronic motor with CORE 6 technology for exceptional energy efficiency. It is specifically designed for in-pond bottom placement in koi ponds — solids-handling up to 3/8" particles, thermal overload protection, frost protection for year-round continuous operation. It's the pump that powers the Atlantic-OASE Clear Water System. Use Waterfall pumps for feature and circulation applications; use AquaMax Eco Premium when the pump needs to sit on the koi pond bottom and pass fish waste to an external filter.
What is the OASE Clear Water Guarantee?
The OASE Clear Water Guarantee applies to correctly sized and specified OASE systems — specifically, a BioTec ScreenMatic² filter paired with an OASE AquaMax Eco pump and OASE Bitron C UV clarifier. When operated and maintained correctly, OASE guarantees clear water visible to at least 3 feet depth. The guarantee reflects the complementary function of the three components: the ScreenMatic² handles mechanical and biological filtration, the AquaMax Eco delivers consistent solids-handling flow from the pond bottom, and the Bitron UV clarifier controls free-floating algae. This system is also the technology behind the Atlantic-OASE Clear Water System pond kits available in our Atlantic Water Gardens collection.
What is the FiltoClear "Easy-Clean Technology" and why does it matter?
OASE's FiltoClear 3rd Generation introduced Easy-Clean Technology — a backflush mechanism that allows you to clean the filter and direct waste water out to a drain or garden without opening the filter housing or removing any components. Turn the cleaning handle, backflush runs automatically, then return the handle to the operating position. This is a significant maintenance quality-of-life improvement over older pressure filters that require opening the canister, removing sponges, and rinsing them by hand. It means cleaning is a 2-minute task instead of a 20-minute project, which dramatically increases how often homeowners actually do it — resulting in better long-term water quality.
How do I size an OASE filter for a koi pond?
For koi ponds, use approximately half the listed "no fish" rating as your effective sizing target. A FiltoClear 5200 rated for 5,200 gallons without fish handles approximately 2,600 gallons with light koi stocking. A BioTec ScreenMatic² 18000 rated for 18,000 gallons without fish handles approximately 9,000 gallons with koi. For large koi ponds over 5,000 gallons, step up to the BioTec ScreenMatic² series rather than the FiltoClear — the automated mechanical screen and multi-zone biological filtration are specifically designed for the waste production of a seriously stocked koi pond. When in doubt, size up — more filtration capacity means more stable water quality during peak summer feeding.
Can I use an OASE AquaMax Eco Premium pump with a non-OASE filter?
Yes — the AquaMax Eco Premium uses standard plumbing connections and can feed any compatible external filter within its flow range. It pairs well with EasyPro pressurized bead filters, Atlantic FilterFalls, and other gravity-fed or pressurized filter systems. The key is matching the pump's GPH output at your operating head height to the filter's recommended flow range. OASE's Clear Water Guarantee specifically requires the Bitron C UV clarifier and BioTec ScreenMatic² filter combination with the AquaMax pump — that combination is what qualifies for the guarantee. Using the AquaMax with other filters is valid and effective; it simply doesn't carry the OASE guarantee.
How often should I maintain OASE filters and what's the right approach?
For BioPress and FiltoClear pressure filters: backflush when flow decreases noticeably — in heavy debris seasons this may be weekly, in low-debris periods monthly. The Easy-Clean on FiltoClear makes this a 2-minute task. For BioSmart gravity filters: rinse the mechanical sponge when flow decreases; clean biological media gently and infrequently to protect beneficial bacteria. For BioTec ScreenMatic²: the automated screen handles mechanical maintenance independently. Periodically empty the debris tray, check the sludge drain, and gently clean biological foams inside the filter in pond water. Replace UV bulbs annually even if they still illuminate — output degrades significantly before burnout. The guiding principle: frequent light cleaning of mechanical stages, infrequent gentle cleaning of biological media.
How do I find correct OASE replacement parts for my model?
Start with the exact model name and SKU number printed on your OASE product label or in the original documentation. OASE replacement parts are highly model-specific — impellers, O-rings, sponges, UV bulbs, and quartz sleeves vary by model generation and size. Common replacement items include AquaMax impellers (model-specific), FiltoClear and BioPress sponge sets, UV bulbs for Filtral and BioPress UVC units, and BioTec ScreenMatic² filter foam sets. UV bulbs should be replaced annually — even if they still glow, output typically drops below effective levels after 12 months. Call us at (765) 508-4352 with your model name and SKU and we'll identify the correct replacement part and confirm availability before you order.
