Thanks all for your input. I went ahead and ordered a Nano Cube 6 gal. I plan to research the corals more as it's cycling. I have access to very clean, ozonated and also
RO water at my work so topping off and water changes aren't a big deal to me at all. I look forward to getting some basic corals and I might end up upgrading the lighting, we'll see how it goes.
I looked at the aquapods and other makers but I just can't have a tank that is open like that on the top with my cats. I like the setup of the Nano Cube and the filtration so that's what I went with.
I'll keep you updated of my progress.
