I got an Eclipse 3 hood/tank for Christmas. So only 3 months of experience with it. Not on my favorites list. Quiet and good looking. Limited options for adding anything like HOB or connections for cannister. Don't like how the power head for it hangs and if it is as short lived as most people say it is, it will get some major cutting/modification for other filtration. The blue filter clogged up so very fast (definitely not overfeeding) it went straight to bypass, so I took it out. Also, one of the lights never stays on unless the front hood is open. Changed the light tubes but nothing helped including adjustment of the metal clips for the tube prongs.
