Great for the red sea g2 60. Although I did have to use a spacer for it to fit my tank correctly. That was not down to the product but the thickness of my glass and it does state the size on the items description. It will fit on the side of the aquarium without a spacer if you don't have the recommended glass thickness but does make it a little wonky. It is perfect once a spacer is used and is worth it for the lamp that goes with it. Other than that great quality and does enable the lamp to m be moved to the side when cleaning. In case anyone has the same tank and want to use the same product I have a fluvel evo sea 52l just for reference.
