More light is most definitely NOT a positive here. You have to have a balance of light, CO2, and nutrients.
Think of it as baking a cake. You have to have a balance of flour, sugar, eggs, chocolate, etc. If you go hog-wild and add 12 eggs to one batch of cake mix, that's gonna be one crappy cake.
Same thing here. 96w of lights over a 10 gallon tank is your problem. To put it in perspective, I have only about 80w over my 40 gallon tank. Lower your light output to one or two bulbs. Dose ferts. Keep up the CO2.
