Frequently Asked Questions

Q: Which Bubble Magus automatic roll filter models is this replacement roll compatible with?

A: This filter roll replacement is specifically designed to fit the Bubble Magus ARF-S, ARF-M, and ARF-L automatic roll filter units. Be sure to select the correct size (A, B, or C) that matches your specific ARF model for a perfect fit.

Q: How often should I replace the aquarium filter roll?

A: Replacement frequency depends on your tank's bioload and feeding habits. A heavily stocked reef tank may require more frequent changes, while a lightly stocked system may go longer between rolls. Monitor the white filter roll — when it becomes visibly brown or clogged with debris, it's time to replace it. Many hobbyists replace rolls every 1–4 weeks.

Q: What is the difference between Size A, B, and C?

A: The three sizes correspond to the different Bubble Magus ARF filter unit sizes: Size A (9×10 cm) fits the ARF-S, Size B (9×15 cm) fits the ARF-M, and Size C (9×20 cm) fits the ARF-L. Always verify your filter unit model before ordering to ensure the correct size.

Q: Is this filter roll suitable for both saltwater and freshwater aquariums?

A: Yes! These filter rolls provide effective mechanical filtration in both saltwater reef tanks and freshwater aquariums, as long as you are using a compatible Bubble Magus ARF automatic roll filter system.
