Filter-Max Pre-Filter Sponge is designed to extend the life of filter media and cartridges while safeguarding small fish and invertebrates. By attaching directly to an impeller tube or powerhead, it prevents larger debris from entering sand filters, UV sterilizers, or protein skimmers.

• Protection: Keeps small fish, fry, invertebrates, and plant matter from being drawn into the main filter
• Efficiency: Reduces clogging and wear on primary filtration systems
• Construction: High-grade sponge with secure fit on intake tubes
• Maintenance: Easy to clean by rinsing and squeezing in aquarium water to preserve beneficial bacteria
• Performance: Wide surface area promotes oxygen exchange and reduces protein buildup
• Applications: Suitable for freshwater or saltwater tanks, including breeding, betta, discus, and turtle setups
• Utility: Functions as a biological backup filter if the main system is offline
• Tank cycling: Can be transferred from an established aquarium to quickly seed a new setup

The slim-line design provides a less obtrusive appearance compared to many other pre-filters, combining practical function with a cleaner look inside the aquarium.
