Aquarium is liveable now (2006.04.11)

I've replaced old very expensive aquarium dedicated fluorescent light ACADIA to normal 3-phases Phillips light last Sunday. I had been hesitating to replace lights for aquarium because I've paid for it almost 100 USD two years ago. I'd like to belive its performance was still better than normal brand-new light.
I've paid just 7 USD for the normal lights. But the performance of new normal lights are much better than the old expensive high performance lights.
You can see MAKAYA Selowinia(?) that has radial green thin leaves. They look pretty fatique and hardly survived.They look very fresh and vital four days later than replacement.
Now they can stand up. They wanted to lay down.
Now they produce oxygen as a result of photosynthesis. They were barely alive.
Wish them fertilized!
