Well its a 75 gal so Id put two on each end in the back corner. I would assume I could hide it with plants and drift wood and I plan to make the back of the glass black so they would blend in well...
Im just curious of how well the work
Those would have to be some big and tall plants and driftwood to completely hide the filter
. Also, you can't completley submerse an internal filter into the tank. It has the hook AND suction cups so that is will stay stuck to the glass. Sorry if I am mistaking what you are saying...but the filter HAS to hang from the top of the glass.
That said, I think it pretty much works the same as a HOB
or any type of external filter. Allows you to place your tank against a wall instead of having a filter hang on the back, and is also much quieter. The motor and all the running pieces of the filter are underwater...
But, like I said before, I think it is all personal preference
Have fun choosing!
