Not too much lighting. Better to have intense lighting but shorter photo period, than weak lighting on too long.
I'd suggest keeping the LED towards the front, for your shorter plants, and the T8's towards the back for the taller plants.
I have my old SPS reef tank diy LED lighting on my 55 without any problems. Its pumping about 250 watts of full spectrum 3 watt diodes, and I could probably add more lights if I wanted. Once the leaves break the surface that's a different story. They can't grow out of water because the lighting is so iintense.the leaves turn white and stunted.
