FAQ
What is the difference between coarse and fine filter foam?
Coarse filter foam traps larger particles like fish waste and plant debris, while fine foam captures smaller particles. Using both allows better control over water clarity and filtration efficiency based on aquarium conditions.
How often should I replace the filter foam?
Replacement timing depends on aquarium size, number of fish and plants, and observed decline in filter performance. It’s recommended to inspect the foam regularly and replace when it appears worn or clogged.
Is this foam compatible with all BioMaster models?
Yes, this 20 ppi ultra-coarse foam is designed for the OASE BioMaster 250, 350, or 600 models.

The filter foam fits perfectly in my BioMaster 350. It handles the fish waste well and keeps the water clearer. I noticed a noticeable improvement in flow after switching to this coarse foam with my fine foam layer.
Jack Parsons –
Works well with my planted tank. The coarse foam captures big debris without clogging easily. I still need to replace it every 6 months depending on fish activity.

Great addition to my filtration system. The blue color is visible and helps me know when it’s time to replace it. It’s durable and performs better than the original foam I had.
