Well, before, it was just one hood with a 50/50 long fl. bulb, then about a 1-1/2 months ago I added a second hood with 2 50/50 mini's. I only have a 10 gal
(now with 35watts of light), so I am guessing this is what did it, since I have been putting in the same supplements all along and making the same water changes.
(I think I'll add this pic to my gallery)
