Usage Tips

Adjust the Mounting Brackets

• For rimless tanks, adjust the light so it sits evenly on the glass edge.

• For rimmed tanks, fit it over the rim without leaning on fragile plastic edges.

Keep It Dry

• Mount the controller and power adapter outside the tank, and avoid splashing water to protect electronics.

Setting the Right Brightness and Color

• Especially for newly planted tanks or delicate plants, begin on a lower brightness level (30–50%) for a week.

• Once plants show healthy growth and no signs of melting or algae, gradually increase.

Adjust Color Modes Based on Goals

• Strong white + red spectrum boosts plant photosynthesis.

• Blue tones enhance fish colors and make the tank more visually appealing.

• Experiment with different color mixes to balance plant growth and aesthetics.

Use Natural Day Cycle

• Mimic sunrise →daylight → moonlight for less stress on fish and plants.

• Sudden full-power changes can shock livestock, so gradual transitions are better.

Use Fertilizers & CO2 with Light

• Strong lights paired with nutrient dosing and CO2 often yield the best results in planted tanks.

• If you’re using CO2, match peak light intensity with CO2 dosing for consistent growth.

Maintenance & Care

• Wipe off dust or salt creep from the light housing occasionally using a soft, dry cloth.

• Do not spray water directly on the fixture.
