상품 특징

• Designed exclusively for the Jengu M1 Smart Tank — this biological filter cartridge slides directly into the second-stage slot in the back chamber. No cutting, no measuring, no guessing. Just open, rinse briefly, insert, and it fits perfectly every time.
• The physical filter handles what you can see. This cartridge handles what you can't. Ammonia and nitrites — released by fish waste and decaying matter — are invisible, odorless, and deadly even at low levels. The biological filter cultivates nitrifying bacteria that convert these toxins into relatively harmless nitrate, keeping your water chemically safe and your fish free from stress.
• Inside, a 3-in-1 high-porosity bio-sponge provides an enormous internal surface area for beneficial bacteria to colonize. Millions of microscopic pockets give nitrifying bacteria a permanent home. The three-layer structure ensures water flows evenly through the media, maximizing contact between bacteria and dissolved waste for continuous, efficient biological filtration.
• The physical and biological cartridges are designed as a system, not stand-alone solutions. The physical filter upstream traps solid debris — uneaten food, plant matter, waste particles. Without it, the bio-sponge clogs and bacteria lose their working surface. Without the biological filter, ammonia builds up unchecked. Both stages are essential. Physical interception first, biological conversion second — together they form a complete filtration loop.
• Nitrifying bacteria colonies take weeks to establish and minutes to crash. That's why the M1 places the biological cartridge in its own dedicated chamber — downstream of the physical filter, undisturbed by maintenance. When you clean or replace the physical cartridge, the bio-sponge stays in place. Water flow remains constant. The bacteria colony remains intact. No cycle disruption, no ammonia spike, no stress on your fish.
• After installing a new cartridge, open the Jengu App and tap Filter Reset. The M1 tracks the replacement cycle automatically and sends a notification when the next change is due. No calendar marks, no memory tricks, no second-guessing whether it's been two months or four.
• We suggest replacing the biological cartridge every 180 days. But the real judge is your water. If ammonia and nitrite readings stay at zero and the sponge structure remains firm with no visible degradation, you can extend use. If water parameters shift or the sponge begins to break down, replace sooner. Let your tank tell you when it's time.
