NOTE:This product must be used with a air pump(pump not included),Need to configure an air pump to generate bubbles.
Features:
Fully Waterproof, totally 3 layers sealed design for underwater work.
1x Bubble LED tube
Pump is not included!!!
Note：
This product is not equipped with an air pump; please equip yourself with an air pump
The reason why bubbles cannot appear:
1. The power of the air pump is related to the depth of the fish tank. The deeper the water, the greater the water pressure.
The more power the air pump needs to be equipped with. At least the pressure applied by the air pump is greater than the water pressure,
so that bubbles can be generated smoothly.
2. If the bottom of the fish tank is covered with fine sand, or if there are many suspended substances in the water quality,
when the air pump is not working, the air chamber of the lamp body will be filled with water, and some suspended substances will
be brought in, causing the air vent to block.
What we can do is to take out the lamp (not in the water), and use the medium-soft brush to clean the air outlet when the air pump is working.That will help.
3. When the air pump is not working, the air chamber of the lamp body will be filled with water. After the air pump is working again, the bubbles will be delayed,
because the air tank is also filled with water and the pressure is increased.
