Does nothing. This is bad. I made one myself with the lights and power supply (which worked really well) and foolishly got rid of it, thinking it was less bulky and that it was a 'good' brand. This is crap and borderline useless. I really regret buying this and almost everything in my tank is Fluval including the 407 in my 37 gallons which I am happy with. It's frustrating to find a brand that makes 80 percent of their products the best in the line and 20 percent that they water down with crap to end up making me not trust anything. Just my two cents.
