Frequently Asked Questions
Answers to common concerns about using the sponge filter.
Is this suitable for saltwater tanks?
Yes, the sponge is ideal for both freshwater and saltwater tanks, provided you maintain appropriate salinity levels.
How do I ensure the bacteria thrive?
Ensure proper water flow and stable temperatures. The filter works best when given a period to establish the beneficial bacterial colonies.
Can I use this filter with other types of media?
While it is designed for biological filtration, you can use it as a complementary filter alongside mechanical media to enhance overall water quality.
What is the difference between 3mm and 5mm thickness?
The thickness affects the flow rate and surface area. Thicker options offer greater filtration capacity but may restrict water movement.
