Does Another Light Increase The PAR?

Recommended Posts

Posted (edited)

So, I originally bought a Fluval Aquasky 2.0 for my 75g because I’m doing “low tech/low light” plants. But, by happy accident, I ended up with 2 of them. So, naturally, I added the 2nd one to the tank as well to better light up both front and back. Does this increase the light intensity or PAR? Could I add more “Medium light” plants now that there are 2 lights? Or does it make no difference?

Multiple lights can increase par. In this instance, being a 75g you won't get double, you'll likely get about 125%. as the lights will be spread out, if you put them side by side, you'd get more like 175%.  There are some factors that keep you from getting just double, like light restrike and such. But in general, more lights = more light.
