Replacement filter foam sets for OASE BioTec ScreenMatic² pressurized pond filters. These high-quality foam pads provide multi-stage mechanical and biological filtration, trapping debris while supporting beneficial bacteria colonies that keep your pond water crystal clear.

Key Features:

  • Official OASE replacement foams designed specifically for BioTec ScreenMatic² filters
  • Color-coded foam sets for easy identification and replacement
  • Multi-density foam design for optimal filtration efficiency
  • Provides both mechanical debris removal and biological filtration
  • Works with BioTec's automatic backwash cleaning system
  • Durable, long-lasting foam material

Why Replace Filter Foams:

  • Foams compress and break down over time from use and backwashing
  • Worn foams lose filtration effectiveness and water flow capacity
  • Fresh foams restore optimal filtration performance and water clarity
  • Regular replacement maintains healthy pond conditions
  • Recommended replacement: annually or when foams show significant wear

Frequently Asked Questions

Q: How many foam sets do I need to completely replace all foams in my BioTec filter?
A: It depends on your filter model and which foams you're replacing. For the BioTec ScreenMatic² 18000, you need: 1 set of Blue foams, 3 sets of Purple foams, and 3 sets of Red foams for a complete replacement (7 sets total). For the BioTec ScreenMatic² 38000, you need: 2 sets of Blue foams (the 38000 uses only Blue foams, but requires double the quantity). The color-coded system makes it easy to identify which foams go where in your filter.

Q: Can I replace just one color of foam instead of all of them?
A: While you can replace individual foam colors if only certain ones are damaged, it's best to replace all foams at the same time for optimal performance. The different colored foams work together as a multi-stage filtration system, each serving a specific purpose. If some foams are old while others are new, filtration efficiency won't be optimal. Plus, if one set is worn out, the others are likely close behind since they've all been in use for the same amount of time.

Q: How often should I replace my BioTec ScreenMatic² filter foams?
A: OASE recommends replacing filter foams annually, typically at the start of the pond season in spring. However, the BioTec's automatic backwash cleaning system extends foam life compared to manual-clean filters. Replacement frequency depends on your pond conditions—heavily stocked koi ponds may need replacement sooner. Signs that foams need replacing include: foams becoming compressed and not expanding after backwashing, reduced water flow through the filter, difficulty maintaining clear water, or visible deterioration. The ScreenMatic² system makes backwashing easy, but eventually all foams need replacement.
