That is a nice fixture for sure. I don't know how prices are where you are and how you sit financially but i personally quit buying new fixtures years ago. I get the best for cheap There have to e some reef forums in Australia I am still not sure what "active cooling" means. Are the fans built in ?? Does it have a built in timer ? I think you are payng a lot for looks in that fixture
