natural sunlight cause more coral groth?

makes me happy that my tank is next to a window then i even notice my firefish comes out of his hiding hole when i open the blinds, so the fish notice it as well

 

thats awesome, i can't wait until i get more corals to see if they do the same

 

of course they will... halides and t5 can only produce light at around 600 PAR (photosynthetically active radiation... aka the type of light needed for life) and the sun produces up to 2000 PAR in some places of the world

 

this makes me even more confident that i will be able to keep SPS thriving since they will have access to NSL along with good flow, t5 lighting and supplements if needed

 

metal halides can put out as much light and more than natural sunlight, at least that is what horticulture teaches us. It is why certain plants grown indoors produce a better crop and high quality product.
The sunlight is like a 4 or 6 hundred watt MH. You should be stoked that you are getting natural light because of the wave length and spectrum favorable to the algae growing in your coral and yes on your glass walls too.
Get a uv steralizer and combine N.L. with your saddle kickin lights and grow the next barrier reef

 

Just wanted to add a bit of caution here. More light is not always better. Not every coral comes from shallow waters and too much light can bleach/damage/kill some corals.
There is a good chance that you're not getting a huge amount of direct sunlight through your window (unless it's a really large window that gets direct sunlight), so it's probably not an issue. But you may be getting enough light to trigger the response from corals/fish to open up and wake up for the day.

Just something to think about.

 

Nice thread. K+ to dingo and Puffer!

 

lol that is awesome! its not directly infront of a window but its right next to one, i'll have to look into a uv steralizer so glad i put my tank where i did

didnt think about that, its just one window, its big but not to big, i guess you can say its just a normal bedroom window, so i dont think bleaching will be to big of an issue.

thanks

 

Also Natural sun light will change colour temp through out the day and through out the year. it can drop as low as 5500K and as high as 6500K. In the winter in the norther hemisphere it is possible that the light is as low as 5400K so the light is not beneficial to coral but is to unwanted algae.

I would love to read up on that, I cant stop reading about marine biology every since 1995
