Had the nano version of the tunze for my Red Sea 130 (34 gal) and didn't like it. The magnet wasn't strong enough. It did an OK job of getting film off the glass, not much else. Other than working at the sand line, the mag float cleans with greater efficiency.
With my new tank, 5/8" glass, I decided to give the full size strong version a go. Tunze is not kidding when they claim 'strong'! This thing will crush a finger if it got inbtween the magnets. It cleans very well and doesn't pick up sand, enough bite to clean tough build up.
A little pricey, but it works!
