Filter Max II Foam Sponge Prefilter for Aquariums up to 20 Gallons

Pre-filters are essential to prevent large particle waste, small fish, baby fish, invertebrates, plant leaves and other undesirables from getting inside and clogging the main filtration system. Pre-filters save on the wear and tear of your main filter. Most pre-filter sponges are flimsy and will either be constantly falling off, clogging or fall apart quickly. Filter-Max uses a high-grade sponge and solid construction that fits securely onto the filter intake tube. It also serves as a back up system if the main filter needs to be shut down, and can be used with most powerheads to cycle a new aquarium immediately when transferred from an established aquarium. The Filter-Max has better aesthetic value than many other pre-filters. It appears slim-line and doesn’t stick out like a sore thumb!

Key Features

• ✅ Extend filter media and replacement cartridge life while protecting small fish; simply connect to your impeller tube or powerhead to keep larger debris out of a sand filter or protein skimmer.
• ✅ Trusted by casual hobbyists and pros alike - whether part of an internal or external power filtration system, the Filter Max is a great introductory point to sponge filters.
• ✅ Whisper-quiet and easy to clean - simply rinse and squeeze in used tank water (not tap water!) to maintain nitrogen-fixing in freshwater or saltwater.
• ✅ Soft foam filters across a wide surface area, creating bubbles to reduce protein buildup and increase oxygen. Ideal for low-current breeding, betta, discus, and turtle tanks.
• ✅ Fast-cycle a new tank by transferring a filter sponge from old to new. For even more pristine water try our Hydro-Sponge Pro line.
