Required Accessories:
1、A 370 silent air pump (1 unit)
2、A PWM speed controller (1 unit)
3、A Type-C waterproof female connector (1 unit)
4、An air stone (1 unit)
5、Air tubing with a 4mm inner diameter (length as needed)
6、Four M2*6 countersunk screws (4 units)
7、Four knurled nuts M2*3*3.2 (4 units)
The lid is designed to be quite tight, so the screws and nuts may not be necessary; you could alternatively use adhesive.
Total cost should not exceed 20 yuan
Power via a power bank or directly via USB-5V
For increased intensity, you can increase the supply voltage (although the air pump's applicable voltage is DC3-6V, I have successfully used it with an 8V supply. However, this is not recommended).
I find that a 5V oxygen supply is sufficient for my 20-liter square tank.
⚠️Note: It is best to secure the oxygen pump to the base using hot glue (the PWM speed controller can also be secured with hot glue). This will prevent the pump's vibrations from causing noise from the internal components.
