Q: Is it compulsory to submerge the pump? Can one mouth be connected to a tank while the other releases water

JamieMatt I have mine currently mounted outside of my tank, just make sure it's below water level as it is not self priming.

Q: I own the 20w version but have not successfully got it hooked up yet. Has anyone hooked up this laser (20w Neje) to a Trocen 708c or know how? The 708c uses 5v pwm ttl signal and prior answer indicated it requires 12v signal. Any input on this question would be much appreciated

JamieMatt I have the 3.5W version and its running perfectly with a 3.3v 20khz pwm from a esp32. The 12v indicated is 12v input voltage not 12v ttl.
