1. you turn off the timer (during 3on time), and after water out then shake...
2. when the pump is off (during 3off time), then shake.
which number is correct?
I have seen the thread that when shaking media, the mulm are out, and it can be source of
bacteria or coral (I am not sure), so I think no1 is better than no2.....
Am I correct?
