@firebirdude - Unfortunately those pics are older and I no longer have the original files. Every time I get a new computer I tend to leave the old pictures behind.
@dave willmore - I am not really sure. UV light from what I understand is very harmful to corals and is not at either the 430nm or 640nm peak that most zooxanthellae use for photosynthesis. Assuming that is true, you can block out all light under the 400nm without any issue. If you are really concerned about the amount of useable light entering your greenhouse, you can always pick up a PAR meter and see what you are getting. Anything over 75 is pretty good to grow most corals I've found.
As for SPS, I think they need much more light 200-300 average, and here in the winter we don't get that many days, so the new system is going to rely more on artificial lights than the greenhouse to provide that consistency. Just about every coral that isn't Acropora grows great in the greenhouse. Actually, Acropora grows just fine, it's just brown 10 months out of the year.
@oceanicsquire - I'm glad you like my youtube channel. I need to make some more videos. If you have any ideas, post a comment on my page.
