Installation and Maintenance Tips

1. Position Near the Bottom Corner:
   Install the filter vertically and close to a tank corner to maximize circulation and reduce dead spots.

2. Fully Submerge the Unit:
   Ensure the filter is entirely underwater to avoid airlocks and maintain proper suction.

3. Secure with Suction Cups:
   Use the included suction cups on a clean glass surface. If they loosen over time, soak them in hot water for a better grip.

4. Add Filter Media for Better Results:
   While the unit usually comes with a basic sponge, you can enhance filtration by:

   • Adding activated carbon for odor and discoloration control.

   • Inserting ceramic rings or bio balls to promote beneficial bacteria growth.

   • Layering fine filter floss for crystal-clear water.

5. Adjust Flow Direction:
   If the output nozzle is rotatable or directional, angle it toward the surface to increase aeration and prevent surface scum buildup.

6. Clean Every 2–4 Weeks:

   • Rinse the sponge and internal parts using old tank water (not tap water) to preserve beneficial bacteria.

   • Inspect the impeller and remove any debris or buildup that could reduce flow.

7. Don’t Over-Clean:
   Avoid over-cleaning or replacing all filter media at once—this can crash your beneficial bacteria colony and harm water quality
