N-Clear Nano Manual

Introduction

The N-Clear Nano Fleece Roller Filter is designed for aquarium enthusiasts who need an efficient, low-maintenance solution to remove particulate matter and maintain pristine water conditions. Ideal for both freshwater and marine aquariums, this filter effectively eliminates suspended solids and organic waste, preventing water quality degradation.

Key Features

• Automatic Roller Filtration: high-density fleece advances automatically when clogged, keeping mechanical filtration uninterrupted.
• Highest Compatibility in the Industry: fits nano all-in-one aquariums including IM, Waterbox, UNS, HelloReef, Aquatop, and more; highly reusable.
• Supports Dual Mode: run two filters from a single controller for dual-chamber setups or high bioload systems.
• Freshwater and Saltwater Ready: engineered for long-term reliability in both freshwater and marine environments.
• FDA Food-Grade Fleece Rolls: industry-first rolls made from FDA food-grade material and tested to comply with 21 CFR 177.1630.

How It Works

1. Water Intake: Flow from the aquarium enters the roll filter and is directed across the fleece.
2. Filtration: Suspended debris is captured by the fleece while clean water exits the chamber.
3. Sensor Detection: As debris accumulates, flow slows and the water level rises until the optical sensor is triggered.
4. Automatic Advancement: The motor advances a fresh section of fleece, restoring flow and lowering the water level.
5. Continuous Operation: The cycle repeats, providing uninterrupted mechanical filtration.

Installation

Complete the steps in order. Do not connect power until the assembled filter is seated in the chamber, the controller is dry, and every plug is fully inserted.

Step-by-Step Installation

1. Install the Sensor: Slide the optical sensor into the sensor bracket on the inner frame until it is fully seated. Route the cable upward so it cannot rub against the fleece or shafts.

   

2. Install the Water Barrier: Fit the water barrier into the lower frame slots. Start with the longest pre-installed barrier unless the matching adapter example specifies the 2.35 in (6 cm) barrier.

   

3. Align the Motor and Take-Up Shaft: Rotate the motor coupling until its D-shaped opening matches the D-shaped take-up shaft. Push the parts straight together; do not force them while misaligned.

   

4. Mount the Motor: Seat the motor assembly on the upper frame mount and install the retaining hardware. Confirm the motor is stable and the shaft turns freely.

   

5. Load the Fleece Roll: Insert the feed shaft through the clean fleece roll and place the shaft into the upper frame supports. The fleece should feed smoothly toward the lower path without twisting.

   

6. Thread and Secure the Fleece: Follow the illustrated path through the frame, then attach the adhesive end squarely to the take-up shaft. Remove all slack before operation.

   

7. Insert the Inner Frame: Lower the fully assembled inner frame into the outer case. Confirm the barrier, sensor cable, and fleece remain in position and that the frame seats completely.

   

Dual Mode Setup (Optional)

The N-Clear Nano Filter supports Dual Mode, allowing two filters to operate from one controller, one power adapter, and one sensor. Both motors advance together when the sensor on the main filter is triggered.

Connect the splitter cable to the controller's motor port, then connect one filter motor to each splitter output. Connect the sensor to the main filter as shown.

Extension Unit Components

Adapter Installation

Install the adapter after assembling the filter and before tuning the sensor. Innovative Marine installations generally do not require an adapter; most other AIO tanks require the N-Fit model made for that chamber.

Choose the Correct Water Barrier

Example 1 — S8080

1. Seat the adapter: Place S8080 squarely on the tank's existing support bumps or blocks and confirm it is level.
2. Match the barrier: The water barrier must meet the edge of the S8080 opening with no bypass gap. Most S8080 installations use the 2.35 in (6 cm) barrier.
3. Install the filter: Lower the filter fully into the adapter and confirm all incoming water is directed through the fleece.

Example 2 — S8075

For AquaTop tanks, use the S8075 adapter and the chamber support point shown in red.

1. Position S8075: Orient the adapter as shown and rest it at the red support bump.
2. Match the barrier: Choose the water barrier whose top edge matches the S8075 opening.
3. Install the filter: Lower the filter fully, then confirm the adapter sits level and has no bypass gap.

Example 3 — S8085 / ReefCasa

1. Start with the base: Use the bottom S8085 layer by itself for most ReefCasa tanks.
2. Add height only if needed: Install the middle riser when the adapter must sit higher, including chamber generations that need extra height.
3. Seal side gaps only if needed: Add the top piece when a test fit leaves an open gap on the left or right side.
4. Match the barrier: Test-fit the selected stack, then choose the water barrier whose top edge matches the adapter opening.
5. Install the filter: Lower the filter fully and confirm the assembled adapter is level, stable, and sealed against bypass.

Example 4 — S8080H / Hang-On

1. Orient the arms: Point both hanging arms toward the chamber wall.
2. Hang the adapter: Lower S8080H until both arms are fully seated and the adapter hangs level.
3. Install the filter: Lower the filter into the adapter opening.
4. Match the barrier: Choose a water barrier whose top edge matches the adapter opening while remaining below the outlet weir.
5. Confirm the seal: Verify the adapter is stable and water cannot bypass around the fleece chamber.

Controller Version Overview

The controller provides real-time feedback on filter status. V2 is the current controller supplied with new units; V1 remains documented for earlier units still in service.

V1 Controller Guide

V2 Controller Guide

The V2 controller is the current controller for new N-Clear units. It uses Default, Long Delay, and Timer Modes.

Adjusting Water Level and Sensor Position

The stable operation of the filter depends on several key factors. When using it for the first time, follow each step carefully and be patient with adjustments.

Set the Aquarium Water Level

Set the initial water level inside the filter to about one inch below the emergency overflow (refer to the video above for a visual guide). Since evaporation can cause water levels in the sump and display to drop, it is recommended to use an ATO system to maintain consistent water levels and stable operation.

Choose the Water Barrier

Most setups perform best with the longest pre-installed water barrier. For hang-on installations, switch to a shorter barrier so that its top edge sits just below the outlet weir. This keeps the chamber sealed and directs all water through the fleece for proper filtration.

Adjust the Sensor Height

1. Start high: Set the sensor to its highest position.
2. Wait for the fleece to get dirty enough: Run the filter for about 12 hours, or up to 24 hours for tanks with a light bioload, until the fleece darkens and the internal water level rises significantly.
3. Lower the sensor gradually: Lower the sensor a little at a time until the sensor tip just touches the water.
4. Confirm the trigger: Wait up to 40 seconds. The motor should trigger, the fleece should advance, and the water level inside the filter should drop as clean fleece replaces the dirty clogged fleece.
5. Keep that height: The point where the sensor first triggers properly is the optimal sensor height.

Troubleshoot Steps

Use the guides below to resolve the most common issues.

Problem 1: Filter never advances

• Confirm pump flow is between 100 and 300 GPH.
• Make sure there is no gap between the filter inlet and the aquarium outlet.
• Lower the sensor a little at a time until the fleece advances.
• Check the aquarium water level and top off if needed.
• Inspect and clean the sensor.

Problem 2: Rolls too frequently or triggers alarms

Work through these steps in order:

1. Check the installation: Confirm the adapter is installed correctly and fully seated so all flow passes through the fleece.
2. Check the mode: Start with Default Mode (MODE LED off). Use Timer Mode only when sensor-based triggering is not possible.
3. Verify connections: Reconnect the sensor, motor, and controller plugs. Ensure connections are secure.
4. Reset the sensor height: Move the sensor to the highest position.
5. Set initial water level: Remove some water until the level inside the filter is about 1/2 inch below the sensor tip. This leaves room for the water level to rise and fall as the fleece clogs and advances.
6. Run for 24 hours, then assess:
   • Case 1: Fleece is dark/dirty and the filter never rolled. Lower the sensor gradually until it just touches the water and triggers a roll. The water level should drop immediately—leave the sensor there. This is the optimal sensor position
     All set!
   • Case 2: The filter rolled and the used fleece is dirty (yellow to brown). Keep the sensor at the top; that is the optimal sensor position.
     All set!
   • Case 3: The filter rolled but the fleece is nearly clean or almost used up. Repeat these steps carefully. If it still over-rolls, contact support.

Problem 3: Motor or controller loses power, flickers, or shuts off

Use this check if the controller lights dim, flicker, restart, or shut off when you press MANUAL or when the motor is connected.

1. Stop running the motor repeatedly: Disconnect power before inspecting plugs or moving the filter.
2. Reseat and dry the connections: Confirm the sensor, motor, controller, and power adapter plugs are fully seated. Keep the controller and power adapter dry.
3. Check the motor load: If the controller stays on with the motor unplugged but flickers or shuts off when the motor is connected or manually advanced, the motor may have a short. This can happen if water gets into the motor. Do not keep testing under power; contact support with a short video of the behavior.
4. Check the controller and power path: If the controller stays dark even with the motor unplugged, check the outlet, power adapter, and barrel connector. If it still does not power on, contact support for controller or power diagnosis.
