I have learned a lesson on lighting the hard way.
I refused to buy "expensive" compact florescent bulbs when I could buy MUCH cheaper ones at certain internet venders. Whne I got these bulbs they looked great. I told everyone about them. I asked people why they would pay twice as much for the same product with a name brand. I said they were just as good as any other. Boy was I wrong. They intially went over my custom 20 gallon. Corals started growing well, but so did the cyano. I tried my best to remove phosphates(which tested 0), ran carbon, almost bought a skimmer. Finally, I decided just to set-up another tank. In the new tank I am using high quality T5s and have almost no cyano(one spot that held over from the 20, it seems to be getting better).
So now I had this CF lighting set-up that I wasn't using. Well I decided to use it over the fish only fuge. Before I was using some NO florescents. There were a few spots of cyano, but not that bad. This morning I checked the fuge and OMG with the CF lights the entire fuge is covered with red slime. I am not happy. Now I have to figure out a different lighting solution.
Moral(as I see it): buy good bulbs it will save you money and heartache.
