Understand your choice of Finnex- I researched AIO's for a while and Finnex was one of my top choices. Finally bought a 28 HQI Nanocube and I couldn't be happier. The light is fantastic, everything worked, there's more of a customer base for discussion and parts availability, and I was able to modify the rear chamber to grow Chaetomorpha for nitrate/phosphate removal. The skimmer is the weak link, but does an ok job. Look at it again- you can buy it locally and it makes a beautiful system.
