Tried twice to get a Nanobox fixture shipped to Canada and nothing but delays and excuses. It was a nightmare. I waited nearly 2 months for my last order and said F* it and asked for a refund. The owner was good about refunding my money though.
I ended up going with a Kessil for my tank and couldn't be happier! The shimmer is out of this world and no unsightly disco! The only issue is now that I have a Kessil, every other LED fixture looks very 'disco-ey' (color banding and you can see the individual colors on the rock/sand) So i'm a Kessil guy from here on out. Or at least a dense matrix led guy
I run mine with a Bluefish controller which is awesome.
1x360we may not be enough for the 250, unless you are okay with lower light corals on the edges of the tank. The again these fixtures are pretty darn powerful. What corals are you planning to keep?
