What's the difference between mine and e ultra sun?

Primarily, the colour temperature which is measured in Kelvin. The Flora-Sun is 5500K (kelvin), the UltraSun is 6500K. So the "colour" of the 5500K is warmer than the 6500K, which is cooler than the other. Warmer means more red, less blue; cool means more blue, less red.

The colour is to some extent just a matter of personal preference. But it does go a bit deeper, because plants do grow a bit better under 6500K. It is thought to be the additional "brightness" of the yellow/green wavelength that is missing in the warmer light. Fish colours also tend to be more natural, because this light is closer to natural sunlight.

So would you then still recommend floating plants? Are those the semi aquatic kind? Or just floating?

Floating plants, as those in our profiles under that section
Floating Plants
or there are a few of the stem plants that can be left floating.

I agree with everything Byron says (mainly 'cause he's correct!)

The Ultrasun gives significantly more light at the substrate (20-40% more depending on depths I've measured with a meter) than the Florasun and using the Ultrasun, you'd be fine with a nice floating plant cover as well. Enough light would penetrate to grow some nice chain swords in there. Absolutely ditch the salt.

Be cautious regarding big-box pet store advice. First question to casually ask the person helping you is "how many tanks do you have at home?" If the answer isn't 2 or more, they may not know anything about fish! I've had both great advice and horrible advice from pet store employees over the years.
