Tunze nano's and hydor koralia's may also be options for you, however both cost more than a maxi-jet (tunze in price, koralia in size)
I personally am saving up for some tunze's as the koralia model 4's are too big IMO.
If you are concerned with hydro usage a maxi-jet 900 is a better choice than a 1200 . a 900 uses 9.9v and a 1200 uses 20v and the GPH is within 65 gallons of each other.
Hope this helps a bit
