does corraline algae need sufficiant lighting to grom

hey guys. so i have a fowlr tank. i only have 40watts of light for 30 gals. i have live rock with corraline algae on it which im trying to make grow better. i am keeping my water parameters in check and calcium at 420ppm.
will the low lighting i have affect its growth. is there sufficiant lighting for the live rock to grow various organisms etc.
thanks

 

the coraline should still grow IME
What might happen is , if in future you upgraded your lights
you might experience a lot of coraline die off (turns white)
it will then start developing again once its accustomed to the more intense ligting

I had coralline grow with 40W in a 60 gallon tank.

+1 to it dieing with a lighting upgrade IME.

 

Yes back in the old days when we walked 10 miles to school in the snow, we still were able to grow coralline. Only kidding it is a valid question. Growing up, a friend's mother had a SW tank in LA, she used tap water, never dosed, old fluorescent lighting, and had the most beautiful pink and purple coralline I have ever seen.

 

hey! in some places tap water isent bad
ive tested my water multiple times and just seem to get lucky everytime no rodi unit and the tanks been up for a little under 2 years
