It looks like you have an emporer 400 as a filter.
For your setup, this might just work.
Let me explain what I mean...
I use 10g tanks in my garage for QT purposes. It's a little colder than I'd like it down there, but stays usually in the 60s.
Anyway, when I used a maxijet 1200 as the flow in my QT tank, I wouldn't need a heater. The maxi produced enough heat to keep the tank in the mid 70s.
The Emporer 400, when used as flow (all filtration removed) didn't heat the water at all. I had to actually go buy a heater to get it up to the temp I wanted.
Point being, you've a lot of light over a small amount of water, which will inevitably heat the tank. It's a good thing to have a filter that doesn't, in this case.
With the Emporer, there are a few things to watch for, though...those pads get filled up with crap very easily and need to be rinsed out. When I used mine, I didn't use the bio-wheels (known to be nitrate factories) or the carbon/sponges. I just took some rock rubble and put in them. The spray bars I replaced with hoses that go down into the rock rubble section.
Anyway, food for thought. Looks like a good start, none-the-less.
