Unfortunately the e-lite has no controllability at this time. It's either on or off. Elos has been developing some really cool lighting for the e-lite but it's not out yet and no know really knows if it ever will be. I have been trying to find the thread here where someone had LED spotlights mounted above their tank. I want to do the same, to add some blue highlights to certain parts of the tank. I can't find the thread though.

The pumps that come with the elos are not noisy at all. The system itself is extremely quiet. However I'm running an external euro reef skimmer in place of the stock elos skimmer, and the sedra pump is pretty loud.

The heat was from the heat wave we had here, and lack of circulation in my house. I have since bought an industrial fan which blows directly at the tank, and temps stay at room temperature... so the pumps and e-lite really don't add any heat to the tank.
