Has anyone tried these? I am starting to add rock and fish to my 120 gallon cube (thanks Jason at A.D.) I would like to get rid of all the brand ner hydors that I bough and use a wave box. My question is the cube is 30" x 30". Is this too short for a wave box? Aby ideas? BTW I will be selling my 100 with custom stand and canopy for a rightous price within a week.
