Oase BioSmart 5000, 10000 REPLACEMENT Filter Foam
Replacement filter foam sets for OASE BioSmart 5000 and BioSmart 10000 gravity-fed pond filters. These high-quality foam pads provide multi-stage mechanical and biological filtration, trapping debris while supporting beneficial bacteria that keep your pond water clean and clear.
Key Features:
- Official OASE replacement foams designed specifically for BioSmart filters
- Three types of high-surface area foam for exceptional biological filtration
- Multi-stage filtration removes debris and processes ammonia and nitrites
- Easy-Clean system—no need to remove foams for routine cleaning
- Durable, long-lasting foam material
Why Replace Filter Foams:
- Foams compress and break down over time from use and cleaning
- Worn foams lose filtration effectiveness and biological capacity
- Fresh foams restore optimal water flow and clarity
- Regular replacement maintains healthy pond conditions for fish
- Recommended replacement: annually or when foams show significant wear
BioSmart Easy-Clean System:
BioSmart filters feature an innovative Easy-Clean system with cleaning handles. Simply pull up on the handles to squeeze debris from the foams without removing them—no need to get your hands dirty! However, even with this convenient cleaning system, foams eventually wear out and need replacement for optimal performance.
Two Models Available:
Foam Set for BioSmart 5000
- Fits: OASE BioSmart 5000 gravity filter
- For ponds up to 5,000 gallons (light fish load)
- Complete set of three foam types
Foam Set for BioSmart 10000
- Fits: OASE BioSmart 10000 gravity filter
- For ponds up to 10,000 gallons (light fish load)
- Complete set of three foam types
What's Included:
- Complete set of replacement filter foams for your specific BioSmart model
- All three foam types needed for proper multi-stage filtration
Note: Make sure to select the correct foam set for your BioSmart filter model (5000 or 10000). Each set is designed specifically for its corresponding filter and is not interchangeable.
Frequently Asked Questions
Q: How often should I replace my BioSmart filter foams?
A: OASE recommends replacing filter foams annually, typically at the start of the pond season in spring. However, replacement frequency depends on your pond conditions—heavily stocked koi ponds or ponds with lots of debris may need replacement sooner. Signs that foams need replacing include: foams becoming compressed and not expanding after cleaning, reduced water flow through the filter, difficulty maintaining clear water even after using the cleaning handles, or visible deterioration and crumbling. The Easy-Clean system extends foam life by making regular cleaning easy, but eventually all foams need replacement.
Q: Do I need to replace all three foam types at once?
A: Yes, it's best to replace the complete foam set at the same time. The BioSmart uses three different types of high-surface area foams that work together as a multi-stage filtration system. Each foam type serves a specific purpose in the filtration process. If some foams are old while others are new, filtration efficiency won't be optimal. Plus, if one foam is worn out, the others are likely close behind since they've all been in use for the same amount of time. Replacing the complete set ensures consistent filtration performance.
Q: How do I know if I have a BioSmart 5000 or 10000?
A: Check the label on your BioSmart filter unit—it will clearly state either BioSmart 5000 or BioSmart 10000. The model number corresponds to the maximum pond size in gallons for a light fish load (5,000 or 10,000 gallons). You can also identify your model by size—the BioSmart 10000 is larger (dimensions: 22"L x 22"W x 16"H for both models, but the 10000 has more internal capacity). If you're still unsure, measure your filter or contact us with a photo and we can help identify your model.
