Is there any rule on how much light to pick for refugium? I am looking for one for a 45G setup with about 4G fuge, 13*9 area.
Does the size like that need as powerful as Kessil H380 (or some grow light with similar 90W output )? Will it be problems if the light is too powerful? Since neither H380 nor most of the led grow light are dimmable, I won’t be able to just turn it down.
