Why isn't my hammer bright green like in the lfs?

So looks like having corals there isn't really a cheaping out, specially on lights. Found some more Taotronic stuff, wondering if these are the same. They look the same and not too expensive. I'm sorry for my ignorance but I want to try to grow corals but don't have the money to do the mega high end lighting stuff, trying to find the correct medium.

Thanks all for all the great info.

So with the water changes, should I be doing 30% biweekly to try to correct the nitrates?
