I second fishpoor's comment about the filter. ALso, the tank specs say wet-dry filter and it comes with ceramic rings and bio-balls but there is no way to keep water in the display section without totally submerging the back sump. Whether this is right or not, who knows, there is no manual and nothing on-line to give you direction either way. I have established a cycle, but have experienced extremely cloudy water for 5+ weeks. I think it has to do with the poor design of the filter.
My tank came with a one page- 2 sided- photocopied set of directions that are virtually useless.
One of my cooling fans is incredibly noisy when it starts up. The tank has only been in use for 6 weeks. Am I going to work on the hood - I'm a newbie, don't really want to.
I also hung a hob on from time to time because the filter will take the better part of a day to handle a disturbance of plant matter, etc.
The other thing is that no-one else (virtually has one) in the freshwater world to ask questions of. I think you might be OK if you are an experienced hand, but I would not recommend one as a beginner.
