Product Features
- 3-Stage Bio-Filtration: Utilizes dense, double-sided mesh sponges (white & black) to filter out debris, fish waste, food residue, plant leaves, and fine particles. Ceramic bio-balls provide biological media for odor absorption, discoloration removal, and waste breakdown.
- Adjustable Water Flow: Features a powerful pump with adjustable flow settings to meet different tank requirements. The pump automatically restarts if power is interrupted and restored.
- Low Water Level Operation: Designed to operate effectively at a minimum water level of 2 inches (5.08 cm), making it ideal for turtle tanks and other low-water habitats.
- Easy Maintenance: Convenient top lid canister allows for quick and easy access for media cleaning and replacement.
- Waterfall Design: The integrated waterfall feature aids in water aeration, enhancing the vitality and interaction of aquatic life.
- 360° Bottom Suction: Ensures stable and sufficient water flow, promoting fast water purification from all angles. The two-tier design is fish-safe.

Setup Instructions
- Unpack and Inspect: Carefully remove all components from the packaging. Inspect the filter unit and media for any damage.
- Install Filter Media: Open the top lid of the filter unit. Insert the dense mesh filter sponges into the designated slots, followed by the ceramic bio-balls. Ensure they are seated correctly for optimal filtration.
- Attach Suction Cups: Secure the provided suction cups to the back or side of the filter unit.
- Position the Filter: Place the filter inside your aquarium or turtle tank, pressing the suction cups firmly against the glass to secure it. Ensure the filter is fully submerged in water, with a minimum water level of 2 inches (5.08 cm).
- Connect Power: Once the filter is securely positioned and fully submerged, plug the power cord into a suitable electrical outlet. The filter should begin operating immediately.
Operating Instructions
- Power On: After proper installation and submersion, plug in the filter. Water will begin to flow from the waterfall outlet.
- Adjust Water Flow: Locate the adjustable flow knob on the top of the filter unit. Rotate the knob to increase or decrease the water flow rate according to your tank's needs and the preferences of your aquatic inhabitants.
- Low Water Level Operation: The IX-90 is designed to function efficiently even with water levels as low as 2 inches. This makes it suitable for habitats where full submersion is not desired or possible.

Maintenance
Regular maintenance is crucial for the optimal performance and longevity of your TARARIUM IX-90 filter. Perform cleaning every 2-4 weeks, or as needed based on tank conditions.
- Unplug the Filter: Always disconnect the filter from the power source before beginning any maintenance.
- Remove from Tank: Carefully remove the filter unit from the aquarium.
- Access Filter Media: Open the top lid of the filter unit to access the filter sponges and ceramic bio-balls.
- Clean Filter Sponges: Rinse the dense mesh filter sponges thoroughly under clean, dechlorinated water. Avoid using tap water directly as chlorine can harm beneficial bacteria. Gently squeeze the sponges to remove accumulated debris. Replace sponges if they are heavily worn or no longer effective.
- Clean Ceramic Bio-Balls: Gently rinse the ceramic bio-balls in a small amount of tank water or dechlorinated water. Avoid excessive cleaning, as this can remove beneficial bacteria.
- Clean Impeller and Housing: Remove the impeller cover and the impeller itself. Clean any debris or buildup from the impeller and its housing using a small brush.
- Reassemble and Reinstall: Reassemble all components, ensuring they fit snugly. Place the filter back into the tank, secure with suction cups, and ensure it is fully submerged before plugging it back in.
