Nutrients

Can lighting itself make nutrients in the tank?

 

Unless your lights are so strong they're bleaching things literally to death, no.

 

I didnt know that was possible.

 

I remember another thread posted by someone that had switched to LED lighting and had noticed a rise in nitrates.I know that the lighting itself cannot produce nutrients in the water column but a lighting upgrade could definitely cause algae to die off possibly releasing nutrients into the system.

 

Only in the extreme, kinda like the example above.
