Just a few personal preferences as I've used similar hobs you are using. The aquaclears are great. When you ready to change out the carbon I found not replacing it and instead find somerthing you can use on top such as floss or one of the hagan pads that will fit the box and use that instead. This will give you better filtering and is much cheaper. Also if the tank shows signs of a surface film add a hagan skimmer and it will do a good job. Keep the tank with a high water level to keep splashing to a minimum.
