Aquatop CAF Classic Aqua Flow Sponge Filter

• A simple, classic, economical aquarium filter
• Tested by breeders and hatcheries for decades
• Less maintenance than traditional filters
• Fast and easy cleaning

Aquatop Classic Sponge Filters feature specially-developed foam material that supports the colonization of beneficial bacteria, providing mechanical and biological filtration. The bio-filtration process breaks down toxic ammonia and nitrites, preserving a clean, healthy habitat for your fish. CAF sponge filters are weighted and easy to install with an air pump or powerhead (sold separately), which provides airlift for silent operation. CAF filters may be used as stand-alone, breeding, or secondary filters, and will fit most external or top filters to act as pre-filtration units.

Directions: When performing routine maintenance, save a portion of removed aquarium water in a fish-safe container. Disassemble the sponge filter and separate the sponge from the hardware. Use the saved aquarium water to clean the sponge. Squeeze it, shake it, and rinse it out in the fish-safe container. When the sponge looks clean, reassemble the sponge filter and reinstall.
